“…Nevertheless, its performance deteriorates during operation at low-speed. The predictive techniques [17], dither signal [18], and modified switching table [19] were proposed in order to solve this drawback. However, these strategies still have some disadvantages related to the hysteresis controllers that can cause the torque and current distortions and limit the steady-state accuracy [20].…”

Abstract:A feasible control strategy is proposed to control a doubly fed induction generator based on the wind energy converter system (DFIG-WECS). The main aim is to enhance the steady state and dynamic performance under the condition of the parameter perturbations and external disturbances and to satisfy the stator power response of the system. Within the proposed control method, the control scheme for the rotor side converter (RSC) is developed on the model predictive control. Firstly, the self-adaptive reference trajectory is established from the deduced discrete state-space equation of the generator. Then, the rotor voltage is calculated by minimizing the global performance index under the current prediction steps at the sampling instant. Through the control scheme for the grid side converter (GSC) and wind turbine, we have re-applied the conventional control. The effectiveness of the proposed control strategy is verified via time domain simulation of a 150 kW-575 V DFIG-WECS using Matlab/Simulink. The simulation result shows that the control of the DFIG with the proposed control method can enhance the steady and dynamic response capability better than the conventional ones when the system faces errors due to the parameter perturbations, external disturbances and the rotor speed.

“…It does not adapt to the motor control of an electric vehicle. Given choices of switching (hysteresis current control or SVPWM) schemes that differ between IFOC and DTC, when the drive controls are decoupled from the switching scheme, differences are more subtle, and indeed IFOC appears to have advantages in terms of dynamic performance and immunity against parameter variations [6]. This paper presents a closed loop speed control of an indirect field-oriented controlled space vector modulated induction motor fed by a ZSI with new control algorithm.…”

This paper aims to achieve the good performances of speed control of the electric vehicle (induction motor) fed Zsource inverter using DSP controller. The electric vehicle (EV) drive must feature fast control response, high efficiency over wide speed and torque ranges. The control technique is a combination of indirect field oriented control (IFOC) and double space vector pulse width modulation (DSVPWM) which combines the advantages of both and simultaneously eliminates certain implementation difficulties. The proposed control method is verified with simulation and the results are analyzed using DSP (TMS320F28335).

“…Direct torque control (DTC) induction motor drive is becoming more popular day by day due to its fast dynamic response and robustness to the variation of the machine parameters without using the current controller [1][2][3][4]. It is evident that the high torque ripple problems allied with the basic DTC system can be reduced by efficiently increasing the output resolution of the inverter.…”

Due to control simplicity and easy applicability DTC has become popular and adopted in many industrial applications. But it still suffers from a few drawbacks like-comparatively large torque ripple in a low speed range and its performance is highly depended on speed of the motor and hysteresis bands of torque and flux ripple. To address these problems, this paper represents a direct torque control (DTC) strategy for induction motor (IM), utilizing hybrid cascaded H-bridge multilevel inverter (HMLI) extending the idea of basic two level DTC proposed by Takahashi. Simulation results shows that the DTC drive performance has been considerably improved in terms of lower torque and flux ripple and less THD. These have been evaluated by simulation and compared with the basic DTC developed by Takahashi and other DTC proposed to date.
