Abstract: This paper is on comparative study of working and variation of different parameters like stability, peak overshoot, rise time, steady state error, etc for different conventional controllers like Proportional (P),Proportional-Integral (PI),Proportional-Integral-derivative (PID) and Fuzzy controllers like Fuzzy logic controller (FLC) and Hybrid Fuzzy PI. Various controllers are designed for speed control of BLDC motor by using different techniques of integration, derivative, Fuzzy Decision making, etc to achieve the desired performance by reducing the peak overshoot, steady state error and sometimes by compromising time taken for computation of loop or memory occupied by controller or cost, etc. A good controller should have reduced overshoot, less rise time and less steady state error. The output response should be approximately similar to input. MATLAB/SIMULINK is used for modeling of motor and implementation of controllers.
Keywords: Brushless DC motor (BLDC), P, PI, PID, FLC, Hybrid-Fuzzy PI controllers.
