HYBRID FUZZY LOGIC PROPORTIONAL PLUS CONVENTIONAL INTEGRATOR-DERIVATION CONTROLLER OF A NOVEL BDFIG FOR WIND ENERGY CONVERSION

Abstract

This paper discusses the control of a new topology of a brushless doubly-fed induction generator (BDFIG) using back-to-back PWM converters and its application to variable speed wind energy generation. The goal of BDFIG control is to achieve a similar dynamic performance to the doubly fed induction generator (DFIG), exploiting the well-known induction motor vector control philosophy. Here hybrid fuzzy logic proportional plus conventional integrator-derivation (Fuzzy P+ID) Controller for a BDFIG used in wind energy systems. The performance of Fuzzy P+ID has been investigated and compared with the conventional PID controller based BDFIG. The simulation results show that fuzzy P+ID controller is superior to PID controller under dynamic condition
