In this paper, new Hybrid Fuzzy controller for Direct Torque Control (DTC) of Induction motor drive has been developed. The newly developed Hybrid Fuzzy controller consists of Proportional-Integral (PI) control at steady state, PI-type Fuzzy Logic Control (FLC) at transient state, and a simple switching mechanism between steady and transient states, to achieve satisfied performance under steady and transient conditions. The features of the proposed new Hybrid Fuzzy controller has been highlighted by comparing the performance of various control approaches including PI control and PI-type FLC for DTC-based Induction motor drives. The pros and cons of these controllers are demonstrated by simulation results. It is shown that the proposed control scheme for DTC-based Induction motor drive is with fast tracking capability, less steady state error, and robust to load disturbance while not resorting to complicated control method or adaptive tuning mechanism. The validity of the proposed scheme is verified by the simulation results. The present work is carried out using Power System Block set, Matlab/Simulink and Fuzzy Logic Toolbox.
