Implementation and Performance Analysis of BLDC Motor Drive by various Controllers

ELECTRICAL

This paper presents design and simulation of ANFIS controller by comparing it with PID and fuzzy for achieving better performance of BLDC servomotor drive. The performance of ANFIS, fuzzy and PID controller-based BLDC servomotor drives is verified under various operating conditions such as, parameter variations, load disturbance,change in reference speed etc. BLDC servomotors are used in, instrumentation systems, space vehicles, electric vehicles,aerospace , robotics and industrial control applications. In such applications, conventional controllers like P, PI, and PID are being implemented with the BLDC servomotor drive control systems to achieve satisfactory transient and steady-state responses. However, the major problem with the general PID controller is that the tuned gain parameters obtained from the BLDC servomotor drive control systems cannot give better transient and Steady-state responses under different operating conditions such as parameter variations, load disturbances, etc. In this paper, design and implementation of ANFIS controller is presented and its performance is compared with PID controller and Fuzzy controller to show its capability to track the error and usefulness of ANFIS controller in control applications.
