Opis:
A control system for a three-phase induction motor was designed with the use of optoelectronic components and methods. Motor speed was controlled by changing supply voltage frequency. This solution ensures a wide range of rotational speeds, constant torque and effective start-up of an induction motor. The designed motor is supplied with direct current converted to three-phase alternating current. The adopted solution relies on renewable sources of energy to produce DC power. The designed electric motor is controlled by changing supply voltage frequency. Input voltage with the desired waveform is generated by the motor’s electronic system that relies on two microcontrollers. The presented solution features a user interface.

Opis:
A universal controller for brushless direct current (BLDC) motors was designed in the presented article. The system is controlled from the user console where operating parameters are set by the user. Signals are transmitted by cables to microcontrollers which control and monitor electric motors. Microprocessors communicate via a data bus. The controller contains the user console module and the motor control module. The user console module generates commands, and motors are controlled and monitored by the control module. Motor control modules operate independently, and each brushless motor has a dedicated control module. Brushless motors can be controlled in bipolar or unipolar mode. The control method is selected by the operator. The user console and motor controllers communicate via the I²C bus.

Opis:
The article presents a device based on the ATmega microcontroller for precise Fiat MultiAir valve-lift system control. The Fiat MultiAir system is the patented electromechanical actuation system of the inlet valves. It allows a control of the inlet valves open time for each combustion chamber independently. The described device has been installed in the Fiat 0.9 TwinAir CNG 80 HP internal combustion engine controlled by the ECU Master open motor controller. As the ECU Master Controller software and hardware does not support Fiat’s MultiAir system control, the above-mentioned device had to be designed. The device consists of the ATmega88 microcontroller, which analyses the signals from the shaft and the cam sensors. Then, the DC converter is powering the solenoid valves of the MultiAir system via two transistors. When the solenoid valve is closed, the incompressible hydraulic fluid transmits the inletcam lobe’s motion to the valve as in a traditional engine. When the solenoid valve is open, the oil bypasses the passage, decoupling the valve, which then closes conventionally via spring pressure. In order to find the specific moments of turning the solenoids on and off the measurements on the original Fiat motor controller have been performed. The acquired oscillograms have been analysed and presented in the article. Studied Fiat 0.9 TwinAir engine is a part of the power generation unit and has been coupled with the three-phase electric power generator MeccAlte 16 kW with an AC exciter.

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:
The aim of this study is to design a control strategy for the angular rate (speed) of a DC motor by varying the terminal voltage. This paper describes various designs for the control of direct current (DC) motors. We derive a transfer function for the system and connect it to a controller as feedback, taking the applied voltage as the system input and the angular velocity as the output. Different strategies combining proportional, integral, and derivative controllers along with phase lag compensators and lead integral compensators are investigated alongside the linear quadratic regulator. For each controller transfer function, the step response, root locus, and Bode plot are analysed to ascertain the behaviour of the system, and the results are compared to identify the optimal strategy. It is found that the linear quadratic controller provides the best overall performance in terms of steady-state error, response time, and system stability. The purpose of the study that took place was to design the most appropriate controller for the steadiness of DC motors. Throughout this study, analytical means like tuning methods, loop control, and stability criteria were adopted. The reason for this was to suffice the preconditions and obligations. Furthermore, for the sake of verifying the legitimacy of the controller results, modelling by MATLAB and Simulink was practiced on every controller.

Opis:
In the paper the conception of CNC system with stepper motor drives is presented. The system consists of a PC computer and a stand-alone CNC controller based on FPGA (Field Programmable Gate Array). In order to eliminate geometric discontinuities of motion trajectory in "G" and "M" codes, special conversion to NURBS (Non Uniform Rational B-Spline) curves on the PC is realized. Additionally, optimization of the motion trajectory feedrate is achieved by using the Look-Ahead algorithm. In the standalone CNC controller the software processor and CLK pulses generator are implemented. CLK pulses with high resolution and varying time period are sent to each of drives independently. An appropriate test to verify the correctness of CNC system was realized.
Na rysunku 1 przedstawiono schemat blokowy proponowanego układu sterowania CNC. Układ może być użyty do sterowania napędami skokowymi jak i serwonapędami. Złożony jest z komputera PC oraz autonomicznego sterownika CNC (rys. 2). Na komputerze PC wykonywane są obliczenia związane z realizacją funkcji interpretera kodu numerycznego, konwertera opisu trajektorii ruchu z kodów "G" i "M" na opis z wykorzystaniem krzywych NURBS (ang. Non Uniform Rational B-Spline) oraz profilowania prędkości parametrycznej z wykorzystaniem algorytmu Look-Ahead. Autonomiczny układ sterownika CNC realizuje zadania związane z generacją sygnałów sterujących CLK z dużą rozdzielczością dla poszczególnych napędów skokowych osi mechanicznych. Opis trajektorii ruchu w kodach G1, charakteryzuje się występowaniem nieciągłości geometrycznych. Proponowanym opisem trajektorii ruchu jest opis z wykorzystaniem krzywych NURBS. Opis za pomocą krzywych NURBS umożliwia minimalizację występowania nieciągłości geometrycznych. Na rysunku 3 przedstawiono przykład trajektorii ruchu, opisanej z wykorzystaniem krzywych NURBS. W celu optymalnego dostosowania prędkości realizacji trajektorii ruchu zastosowano profilowanie prędkości po krzywej "S" z jednoczesną analizą zadanej trajektorii ruchu w przód - algorytm Look-Ahead. Na rysunku 4 przedstawiono budowę autonomicznego sterownika CNC. Sterownik zbudowany jest na układzie FPGA (ang. Field Programmable Gate Array). W układzie FPGA zaimplementowano procesor MicroBlaze oraz układ generacji sygnałów sterujących CLK dla napędów skokowych. Generator impulsów z dużą rozdzielczością oblicza okresy impulsów CLK dla każdej z osi i niezależnie wysyła je do napędów skokowych. Badania układu CNC miały na celu sprawdzenie poprawności działania aplikacji uruchomionej na komputerze PC (algorytmu Look- Ahead i konwersji z kodów "G" i "M" na opis z wykorzystaniem NURBS) oraz komunikacji poprzez port USB. W autonomicznym sterowniku CNC przeprowadzono badania związane z poprawnością przetwarzania otrzymywanych danych z komputera PC poprze port USB. Przykłady trajektorii ruchu w postaci okręgu i linii łamanej opisanej w kodzie G1 przedstawiono na rysunku. 5. Na rysunku 6 przedstawiono oscylogramy impulsów CLK wysyłanych do napędów skokowych.

Opis:
Induction motors (IMs) experience power losses when a portion of the input power is converted to heat instead of driving the load. The combined effect of copper losses, core losses, and mechanical losses results in IM power losses. Unfortunately, the core losses in the motor, which have a considerable impact on its energy efficiency, are not taken into account by the generally employed dynamic model in the majority of the studies. Due to this, the motor rating often corresponds to the worst-case load in applications, but the motor frequently operates below rated conditions. A hybridized model reference adaptive system (MRAS) with sliding mode control (SMC) is used in this study for sensorless speed control of an induction motor with core loss, allowing the motor to operate under a variety of load conditions. As a result, the machine can run at maximum efficiency while carrying its rated load. By adjusting the -axis current in the reference frame in vector-controlled drives, the system’s performance is enhanced by running the motor at its optimum flux. Regarding the torque and speed of both induction motors with and without core loss, the Adaptive Observer Sliding Mode Control (AOSMC) has been constructed and simulated in this case. The AOSMC with core loss produced good performance when the proposed controller was tested.

This paper presents the modeling, control and simulation of an electric vehicle with four in-wheel 15 kw induction motors drive 4WDEV controlled by a direct torque control DTC strategy, where two control techniques are presented and compared for controlling the electric vehicle speed: the first one is based on a classical PI controller while the second one is based on a fuzzy logic controller (FLC). The aim is to evaluate the impact of the proposed FLC controller on the efficiency of the 4WDEV taking into account vehicle dynamics performances, autonomy and battery power consumption. When the classical controller can’t ensure the electric vehicle stability in several road topology situations. To show the efficiency of the proposed new control technique on the traction system by 4WDEV. The vehicle has been tested in different road constraints: straight road, sloping road and curved road to the right and left using the Matlab / Simulink environment. The analysis and comparison of the simulation results of FLC and PI controllers clearly show that the FLC ensures better performances and gives a good response without overshoot, zero steady state error and high load robustness rejection, compared to the PI controller which is present an overshoot equal 7.3980% and a rise time quite important (0.2157 s with PI controller and 0.1153 s with FLC). As well as the vehicle range has been increased by about 10.82 m throughout the driving cycle and that the energy consumption of the battery has been reduced by about 1.17% with FLC.

This paper proposes RT-LAB platform for realtime implementation of Luenberger observer based on speed sensorless scalar control of induction motor. The observed shaft speed is derived from lyapunov’s theory. It is shown by an extensive study that this Luenberger observer with PI anti-windup speed controller is completely satisfactory at (nominal, variable, reverse) speed references and it is also robust to load torque disturbance. The sensorless control algorithm along with the proposed Luenberger observer is modeled, built in the Host PC and successfully implemented in real-time using digital simulator OP5600. The experimental results observed in the GW-Instek digital oscilloscope’s screen validate the effectiveness of the proposed Luenberger observer for speed sensorless scheme.

Opis:
This paper focuses on designing a gain-scheduled (G-S) state feedback controller (SFC) for synchronous reluctance motor (SynRM) speed control with non-linear inductance characteristics. The augmented model of the drive with additional state variables is introduced to assure precise control of selected state variables (i.e. angular speed and d-axis current). Optimal, non-constant coefficients of the controller are calculated using a linear-quadratic optimisation method. Non-constant coefficients are approximated using an artificial neural network (ANN) to assure superior accuracy and relatively low usage of resources during implementation. To the best of our knowledge, this is the first time when ANN-based gain-scheduled state feedback controller (G-S SFC) is applied for speed control of SynRM. Based on numerous simulation tests, including a comparison with a signum-based SFC, it is shown that the proposed solution assures good dynamical behaviour of SynRM drive and robustness against q-axis inductance, the moment of inertia and viscous friction fluctuations.

Opis:
An equivalent sliding mode control method of an induction motor speed has been discussed. The control signal consists of two parts: a continuous and discontinuous one. Very good dynamical response of the drive system has been obtained, which however changes influenced by external and parametric disturbances occurring under various operation conditions. In order to ensure identical dynamic performance of the speed transients and system robustness during the switching line reaching phase, regardless of external and parametric disturbances, the time-varying switching line is proposed. The simulation results have been validated by experimental tests of the induction motor drive system.
