Opis:
Controllers based on linear matrix inequalities (LMI) and model predictive control (MPC) both use optimization methods; there are however significant differences between them. In case of LMI controllers, optimization is carried out during controller synthesis, because LMI’s are an optimization tool that requires a linear programming problem being solved. With MPC controllers, however, optimization methods are not used as much in controller synthesis as in controller algorithm operation, to determine optimal control signal values based on the found minimum of the criteria function. A square function is used with boundaries from above and below, which requires a square programming problem, with boundaries for decision variables, being solved. In this paper controller synthesis methods using LMI and MPC are shown, with a focus on the steps that need to be performed, and a comparison of both methods.

Opis:
The most problem of direct torque control are high torque ripple and Settling time to overcome this problem an efficiency Backstopping speed controller are proposed. This paper makes a comparison of the effectiveness of three PI speed controller based direct torque control, the first one is the classical PI speed controller (CL-PISC), the second are no Adaptive Backstepping controller (NABACKSC), and the third type are adaptive fuzzy PI controller (AF-PISC). The parameters of adaptive fuzzy PI are dynamically adjusted with the assistance of fuzzy logic controller. The non-Adaptive Backstopping controller is designed based on the Lyapunov stability theorem. The direct torque control is very adapted for electric propulsion systems; we apply this new strategy for an 15 Kw induction motor. The proposed PI controllers are simulated in MATLAB SIMULINK environment. The simulation results confirmed that the NA-BACKSC, present robust and the best dynamic behavior on direct torque control compared to AF-PISC and CL-PISC.

Opis:
This article presents a proposal of impedance controller, which is able to infulence the compliance of a robot, based on information obtained from a lowlevel controller about robot interaction with the environment. The proposed system consists of a lowlevel controller with proximity sensor, based on which mechanical impedance is adjusted. The intention of the creators was to develop a universal impedance regulator in the sense of hardware and software layers. Because of TCP/IP architecture, the designed regulator can be easily adapted to different robot controllers. Experiments were conducted on a real 1-DOF manipulator driven by BLDC motor, as well as using simulation on a 2DOF planar robot.

Opis:
The time delay element present in the PI controller brings dead-time compensation capability and shows improved performance for dead-time processes. However, design of robust time delayed PI controller needs much responsiveness for uncertainty in dead-time processes. Hence in this paper, robustness of time delayed PI controller has been analyzed for First Order plus Dead-Time (FOPDT) process model. The process having dead-time greater than three times of time constant is very sensitive to dead-time variation. A first order filter is introduced to ensure robustness. Furthermore, integral time constant of time delayed PI controller is modified to attain better regulatory performance for the lag-dominant processes. The FOPDT process models are classified into dead-time/lag dominated on the basis of dead-time to time constant ratio. A unified tuning method is developed for processes with a number of dead-time to time constant ratio. Several simulation examples and experimental evaluation are exhibited to show the efficiency of the proposed unified tuning technique. The applicability to the process models other than FOPDT such as high-order, integrating, right half plane zero systems are also demonstrated via simulation examples.

Implementation of fuzzification, fuzzy rules and defuzzification techniques allowed the construction of a controller tuned in accordance to expert knowledge as an alternative to the industry PID standard. Both controllers’ structures are analysed. Their verification leads to the assessment and comparison of dynamic properties of a modelled ship’s course control. Further development of course controllers into track controllers has been discussed as well.

The paper presents a procedure of control algorithms hardware-software implementation in a System-on-a-Programmable-Chip based on automatic generation of a code for hardware and software parts and their interfaces from a Simulink model. The developed code generator allows for synthesis of hardware components, compilation of a program with hardware interfaces for the soft-processor and accurate simulation of the implemented algorithm in Simulink. The methodology and tools were verified in a case study of a parallel robot control algorithm. Section 2 contains assumptions for the procedure, Section 3 - its description. Section 4 covers the automation method and describes functions of the code generator software. The automated design flow that includes the code generator is shown in Fig. 2. The code generator products and their use are presented in Fig. 3. The example of the parallel robot controller implementation is given in Section 5. The robot control algorithm scheme in Simulink is presented in Fig. 4. The obtained results show that the differences between the values of the control signal produced in FPGA and those in Simulink (Fig. 5) are smaller than the resolution of the output digital-to-analog converter. It proves that the considered procedure and code generator software correctly transformed the control system from the Simulink scheme. The presented tool enables fast, error free FPGA implementation of control algorithms specified on a high level of abstraction.

Opis:
W celu rozwiązania problemu dokładnego sterowania obiektem nieliniowym, zaprojektowany został rozmyty samonastrajalny regulator cyfrowy PID łączący w sobie zalety układu wnioskowania rozmytego i prostotę regulatora PID. Zaprojektowany regulator składa się z regulatora rozmytego i z regulatora PID. W celu poprawy jakości sterowania, w zależności od wartości uchybu i szybkości zmian uchybu układu regulacji oraz reguł sterowania rozmytego, regulator rozmyty może stroić na bieżąco trzy parametry regulatora PID. Wartości początkowe parametrów regulatora cyfrowego PID wyznaczone zostały z wykorzystaniem klasycznej teorii sterowania liniowego metodą lokowania biegunów. Zaprojektowany regulator zastosowany został do sterowania poziomem wody w dolnym zbiorniku w układzie kaskadowym dwóch zbiorników. Badania wstępne układu sterowania przeprowadzone zostały w Simulinku z użyciem modeli symulacyjnych. Badania docelowe wykonane zostały w układzie sterującym obiektem rzeczywistym z poziomu Matlaba/Simulinka z wykorzystaniem przybornika RealTime Windows Target poprzez kartę wejść i wyjść analogowych PCI-1710, produkowaną przez firmę Advantech. Uzyskane wyniki badań pokazują, że zaproponowany układ sterowania ma mniejsze przeregulowania i krótszy czas regulacji, niż układ sterowania wykorzystujący konwencjonalny regulator cyfrowy PID o stałych wartościach parametrów.
In order to solve the problem of accurate control of the nonlinear system, a digital fuzzy-PID self-tuning controller was designed by combining the advantages of fuzzy inference system and the simplicity of the PID controller. Designed controller composes of fuzzy controller and digital PID controller. According to the error and error rate of the control system and fuzzy control rules, the fuzzy controller can tune the three parameters of the PID controller in order to improve the quality of control. The initial values of parameters of the digital PID controller were determined using classical linear control theory with the pole placement method. Designed controller was used to control the water level in the lower tank in a double tank cascade system. Preliminary studies of control system were carried out in Simulink using simulation models. The target research were made in system controlling the real object using Matlab/Simulink and the Real-Time Windows Target Toolbox through I/O PCI-1710 card produced by Advantech. Presented research results show that proposed control scheme has smaller overshoot and shorter settling time than control system which uses classical digital PID controller with constant values of parameters.

Opis:
Wind and solar radiation are intermittent with stochastic fluctuations, which can influence the stability of operation of the hybrid system in the grid integrated mode of operation. In this research work, a smoothing control method for mitigating output power variations for a grid integrated wind/PV hybrid system using a battery and electric double layer capacitor (EDLC) is investigated. The power fluctuations of the hybrid system are absorbed by a battery and EDLC during wide variations in power generated from the solar and wind system, subsequently, the power supplied to the grid is smoothened. This makes higher penetration and incorporation of renewable energy resources to the utility system possible. The control strategy of the inverter is realized to inject the power to the utility system with the unity power factor and a constant DC bus voltage. Both photovoltaic (PV) and wind systems are controlled for extracting maximum output power. In order to observe the performance of the hybrid system under practical situations in smoothing the output power fluctuations, one-day practical site wind velocity and irradiation data are considered. The dynamic modeling and effectiveness of this control method are verified in the MATLAB/Simulink environment. The simulation results show that the output power variations of the hybrid wind/PV system can be significantly mitigated using the combination of battery and EDLC based storage systems. The power smoothing controller proposed for the hybrid storage devices is advantageous as compared to the control technique which uses either battery or ultracapacitor used for smoothing the fluctuating power.

Opis:
This paper deals with a simulation-based design of model-based iterative learning control (ILC) for multi-input, multi-output nonlinear time-varying systems. The main problem of the implementation of the nonlinear ILC in practice is possible inadmissible transient growth of the tracking error due to a non-monotonic convergence of the learning process. A model-based nonlinear closed-loop iterative learning control for robot manipulators is synthesized and its tuning depends on only four positive gains of both controllers - the feedback one and the learning one. A simulation-based approach for tuning the learning and feedback controllers is proposed to achieve fast and monotonic convergence of the presented ILC. In the case of excessive growth of transient errors this approach is the only way for learning gains tuning by using classical engineering techniques for practical online tuning of feedback gains.

The equation takes into account viscous, surface tension, gravitational forces, capillary entrance pressure and dielectrophoretic force. Numerical calculations have been performed for 2-propanol as a liquid. Time dependence of the height of rise and the velocity of liquid front has been obtained for two cases of the initial liquid height and several values of a voltage applied to the plates.

Opis:
The article deals with the issue of controlling the autonomous mobile systems. Considered are problems focusing around the use of distributed architecture controllers. In contrary to hierarchical architecture, all layers of distributed controller are operating simultaneously, and have an access to both: the sensors (receptors), as well as to the executing systems (effectors) of controlled autonomous mobile system. Simultaneous operation of all layers of the distributed architecture controller entails arising of so called action selection problem. This problem consists in continuous taking of decisions: which one of the layers, or which layers of controller, at given moment should have an influence on the movement of controlled object.

Opis:
The article describes the determination and verification of regulator PID coefficients exampled by regulator which is a part of the control system of pumps for liquids. To implement the identification process we used functions available in Matlab. Obtained in the simulation result amounted to 93.59% of setpoint. The effectiveness of the method is illustrated by the graph allowing comparison of the preset value of the variable capacity of the pump operation with the results obtained from the simulation of the arrangement: the control system - the pump.

Opis:
The article is devoted to the development of a software controller for automation of access to tools and object model of the multifunctional graphic editor Adobe Photoshop. The work of the graphic editor is initiated in the form of a COM object, which contains methods available to the software controller through the COM interface, which allows the software to use the functionality of the editor. To restrict unauthorized access, a software authorization control protocol is proposed, which is based on the use of binding to the computer hardware and encryption by a 128-bit MD5 public key hashing algorithm.

Opis:
This paper presents an abstraction-based technique to solve the problem of distributed controller design enforcing persistency specifications for interconnected systems. For each subsystem, controller synthesis is based on local distributed sensor information from other subsystems. An effective method is presented for quantification of such partial information in an abstraction in terms of level sets of Lyapunov-like ranking functions. The results are illustrated on a laboratory hydraulic system.

Opis:
The paper presents a three-phase grid-tied converter operated under unbalanced and distorted grid voltage conditions, using a multi-oscillatory current controller to provide high quality phase currents. The aim of this study is to introduce a systematic design of the current control loop. A distinctive feature of the proposed method is that the designer needs to define the required response and the disturbance characteristic, rather than usually unintuitive coefficients of controllers. Most common approach to tuning a state-feedback controller use linear-quadratic regulator (LQR) technique or pole-placement method. The tuning process for those methods usually comes down to guessing several parameters. For more complex systems including multi-oscillatory terms, control system tuning is unintuitive and cannot be effectively done by trial and error method. This paper proposes particle swarm optimization to find the optimal weights in a cost function for the LQR procedure. Complete settings for optimization procedure and numerical model are presented. Our goal here is to demonstrate an original design workflow. The proposed method has been verified in experimental study at a 10 kW laboratory setup.

Opis:
The article discusses main problems of implementing the PID control law in the FPGA integrated circuit. Consecutive steps of discretizing and choosing the fixed-point representation of the continuous, floating-point PID algorithm are described. The FPGA controller is going to be used in the active hetero-polar magnetic bearings system consisting of two radial and one axial bearings. The results of the experimental tests of the controller are presented. The dynamic performance of the controller is better when compared with the dSPACE controller, that was used so far. The designed hardware and software, the developed implementation procedure and the experience acquired during this stage of the whole project are going to be used during the implementation of more sophisticated control laws (e.g. robust) in the FPGA for AMB controllers.
