This study compares a proportional-integral (PI) regulator with a parallel proportional-integral (PPI) regulator in a two-level pulse width modulation (PWM) inverter-fed Induction Motor (IM) drive. The IM drive is controlled by a modified field-oriented control (FOC) strategy using the PPI controller to improve performance. The FOC-PPI strategy is shown to be robust and efficient under parametric variations of the IM drive, as demonstrated through numerical simulations in Matlab/Simulink.
This study is a comparative study between a proportional-integral (PI) regulator and a parallel proportional-integral (PPI) regulator for the Induction Motor (IM) drive supplied with a two-level pulse width modulation (PWM) inverter. This motor is controlled by field-oriented control (FOC). However, the proposed FOC strategy is a modification of the classical technique, where the PPI controller was used for this purpose to improve the performance of the IM drive. The designed FOC strategy based on PPI controllers is a robust control strategy and a high performance. The numerical results of the FOC-PPI strategy are compared with the results of the traditional FOC strategy of IM drive at different operating conditions using the Matlab/Simulink environment. Furthermore, the comparison is made in terms of dynamic response, ripple ratio, current quality, and overshoot, and this is in the case of changing or not changing the parameters of the machine. The simulation results illustrate the robustness and efficiency of the suggested FOC-PPI strategy to the parametric variations of the IM drive. (c) 2023 The Authors. Published by Elsevier Ltd.
