Opis:
This paper presents the study and implementation of a new vector control strategy using a hybrid control technique applied to the mechanical position loop aiming to obtain a system that acts in the fractional horsepower motor driver running at near zero frequency. For this purpose, some control techniques are employed to check which one has the best performance regarding this type of application. The use of three control techniques is considered: the Proportional-Integral-Derivative (PID) controller with fixed gain; the Generalized Predictive Control (GPC) controller; and a hybrid controller. The last one behaves as both PID and GPC using fuzzy logic in order to achieve improved system performance. Simulation and experimental results are shown and discussed to demonstrate the merits of the proposed approach.

Opis:
This paper investigates the application of a novel Model Predictive Control struc- ture for the drive system with an induction motor. The proposed controller has a cascade-free structure that consists of a vector of electromagnetics (torque, flux) and mechanical (speed) states of the system. The long-horizon version of the MPC is investigated in the paper. In order to reduce the computational complexity of the algorithm, an explicit version is applied. The influence of different factors (length of the control and predictive horizon, values of weights) on the performance of the drive system is investigated. The effectiveness of the proposed approach is validated by some experimental tests.

Opis:
In this survey paper, resonant and quasiresonant DC link inverters are reexamined for AC motor drive applications. Critical evaluation of representative topologies is based on simulation and waveform analysis to characterize current/voltage stress of components, control timing constraints and feasibility. A special concern over inverter common-mode voltage and voltage gradient du/dt limitation capacity is discussed for motor bearing and winding insulation safety. Experimental records of the laboratory developed parallel quasiresonant DC link inverter feeding induction motor confirm results of analysis. Comparative tables and simulation results demonstrate characteristic features of various schemes.

Opis:
In (his paper, timing and optimization of the proportional and integral (PI) gains of speed controller is achieved using Genetic Algorithm (GA) for improving the performance of the induction motor drive because higher the quality of the controller lesser is the ripples produced in the torque and speed responses. The developed GA program has multi-objective minimization functions. The optimized values of PI gains are incorporated in vector controlled induction motor model for performance analysis during sudden disturbances like speed reversal, load application and load removal. GA tuning method outstandingly surpasses the conventional and most widely used Ztegler Nichols Tuning method. GA tuned PI controller reduces the peak overshoot almost by 60% and quickly brings the system to steady state value. The simulated results obtained from GA tuned PI controller can be realized and validated through experimental results in future work.

In the article, the research results of switched reluctance motor drive performance comparison were presented. The idea of improving the energy performance of the SRM drive through the introduction of modern construction materials of magnetic circuit made from powdered iron in relation to the classic design of isolated, rolled metal sheets was defined. Purposes and motivation of research based on general descriptions of comparable properties of magnetic materials were introduced. The structure of a novel motor drive with developments in the implementation of control algorithms imply the possibility of a fair comparison, which is the subject of the publication. The actual state of research, its methodology and the results of studies were described with an emphasis on aspects of energy consumption in static and dynamic states of drive work. In conclusion, an attempt to determine the validity of the main idea was made and area of further research was outlined.

Opis:
Modern methods of motor drives control are ought to be high precision and quality. This quality is achieved through a rapid and accurate realization of given electromagnetic torque which is insensitive to inverter voltage changes. As a result of using such control methods, a whole system can be considered as an element on constant power for constant angular velocity of the rotor, which leads to occurrence of negative admittance in presence of voltage changes. When an inverter input filter has a high inductance value, negative admittance leads to the excitation of input filter voltage oscillations, whose amplitude often exceeds 50% of nominal voltage. Such a perturbations of inverter voltage can lead to unstable work of electric drive or to damaging one of the inverter elements. The article outlined a method for stabilizing an inverter voltage, through an additional admitance which compensates an unstable component of system. Theoretical considerations and practical algorithm are included. As confirmation of the high efficiency of the proposed algorithm, article contains computer simulation, tests and results.

Opis:
This paper proposes two high-order sliding mode algorithms to achieve highperformance control of induction motor drive. In the first approach, the super-twisting algorithm (STA) is used to reduce the chattering effect and to improve control accuracy. The second approach combines the super-twisting algorithm with a quasi-barrier function technique. While the super-twisting algorithm (STA) aims at the chattering reduction, the Barrier super-twisting algorithm (BSTA) aims to eliminate this phenomenon by providing continuous output control signals. The BSTA is designed to prevent the STA gain from being over-estimated by making these gains to decrease and increase according to system’s uncertainties. Stability and finite-time convergence are guaranteed using Lyapunov’s theory. In addition, the two controlled variables, rotor speed, and rotor flux modulus are estimated based on the second-order sliding mode (SOSM) observer. Finally, simulations are carried out to compare the performance and robustness of two control algorithms without adding the equivalent control. Tests are achieved under external load torque, varying reference speed, and parameter variations.

Opis:
This article presents a simple technique of identifying the initial speed that allows for restarting a sensorless induction motor (IM) drive controlled by a model predictive flux control (MPFC). Initial speed identification is required because, according to the research, the applied current-model reference adaptive system (C-MRAS) can restart the IM after failure only if the error of the initial speed set in the estimator is < 25%. The proposed technique is based on short periods of flux generation for the certain initial speed and observation of the estimated torque respond. The direction of the estimated torque determines whether the real speed is higher or lower than the initial one set in the estimator. In two steps, the algorithm identifies the initial speed with an accuracy of 25%. This allows for a quick restart of the IM from any speed, eliminating the disadvantage of the sensorless drive control system with the C-MRAS speed estimator. The experimental results measured on a 50 kW drive which illustrates the operation and performances of the system are presented.

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.

The paper presents a sensorless control approach for a five-phase induction motor drive with third harmonic injection and inverter output filter. In the case of the third harmonic injection being utilised in the control, the physical machine has to be divided into two virtual machines that are controlled separately and independently. The control system structure is presented in conjunction with speed and rotor flux observers that are required for a speed sensorless implementation of the drive. The last section is dedicated to experimental results of the drive system in sensorless operation, and the uninterrupted drive operation for two open-phase faults.
