摘要

This article presents an improved predictive torque control scheme for an induction motor (IM) drive by incorporating auto tuning feature. Among the variant control techniques, predictive torque control for an IM drive is the real choice for high dynamic performance and it became more popular since it involves control parameters in cost function. Weighting factor adjustment in cost function has direct influence in the performance of a drive. The main problem associated with the conventional predictive torque control scheme is the selection of convenient weighting factors to accomplish optimal torque and flux response. To overcome this problem, auto tuning of weighting factor based on control objective is introduced. With this, optimal weighting factor is selected for cost function evaluation in every sampling time, thereby giving desired performance. To validate this, MATLAB/Simulink and experimental results are presented for an IM drive fed by two level voltage source inverter. These results establish that proposed control scheme of IM drive exhibits optimal torque and flux response.
