Performance Estimation of LCL-T Resonant Converter with Fuzzy/ PID Controller Using State Space Analysis

C. Nagarajan and M. Madheswaran

Abstract—This paper presents a comparative evaluation of Proportional Integral Derivative (PID) Controller and Fuzzy Logic Controller (FLC) for a modified LCL-T (inductor capacitor inductor) Series Parallel Resonant Converter (SPRC) has been simulated and the performance is analysised. A three element LCL-T SPRC working under load independent operation (voltage type and current type load) is presented in this paper. The analysis is carried out using the state space approach and the regulation of output voltage is done by using Fuzzy controller and PID Controller. The simulation study indicates the superiority of fuzzy control over the conventional control methods. The MATLAB simulated results show that the output of converter is free from the ripples, constant current, regulated output voltage and these converters can be used for many airborne applications.
