Abstract: Quasi ZSI are used for induction motors operating at low input voltage. This work deals with comparison of FLC & PI controlled current fed quasi ZSI fed IM drive systems. Open loop and closed loop systems are simulated by considering step change in load. The results of open loop and closed loop systems are compared. The objective of this work is to improve the dynamic response of CFQZSI using FLC. The time responses of PI and FLC controlled closed loop systems are also compared. Fuzzy logic controlled system is proposed to improve the dynamic response of CFQZSI fed induction drive system. Design and simulation results are presented to demonstrate the new features. FLC is observed to provide better control the another controllers and it also has improved damping characteristics. The hardware is fabricated and the experimental results are compared with the simulation results.
Keywords: The dynamic response of CFQZSI using FLC.
