Simulation and Analysis of Intelligent FLC for BLDC Drive

Abstract

This paper presents the performance of the Brushless DC Motor (BLDC) using Intelligent Fuzzy Logic Controller. The mathematical model of BLDC drive is proposed. Usually fuzzy logic controllers are poor under load disturbances and transient conditions. To enhance the dynamic performance of the BLDC drive, a novel implementation of speed controller based on modified fuzzy logic control is presented which is termed as Intelligent FLC. A complete simulation of closed loop BLDC drive using Intelligent FLC is simulated successfully using MATLAB / Simulink. The entire BLDC model simulation is divided into the several independent functional modules such as BLDC module, current control module, PWM module inverter module and so on. The simulation model of the BLDC Drive simulation can be obtained by combining these modules. In order to verify the effectiveness of the Intelligent FLC, the simulation results are compared with other controller (PI and FPI controller). The simulation result shows Intelligent FLC has superior performance than PI and FPI controller.
