A RELIABLE MATRIX CONVERTER FED INDUCTION MOTOR DRIVE SYSTEM BASED ON PARAMETER PLANE SYNTHESIS METHOD
The paper presents a novel technique for designing Proportional Integral (PI) controller parameters for a reliable closed loop operation of Matrix Converter (MC) fed Induction Motor Drive (IMD). Parameter plane synthesis method is used to find the stable region in PI parameter plane. Small signal stability of the system is tested by perturbation along the stable point. The frequency scanning technique is used to confirm the stability of the region in parametric plane. The theoretical investigations have been carried out for analyzing the steady state and transient behavior of the proposed drive system and compared with the conventional Ziegler-Nichols method.
