PSO Based PID Controller for BLDC Motor
International Journal of Innovative Research in Science Engineering and Technology
Brushless DC Motor (BLDC) has more advantages like high efficiency, speed ranges, long operating life, compactness, less maintenance. The BLDC motor performance can be controlled and improved by using controller .The Proportional-Integral-Derivative (PID) controller is the most common and useful method in most applications for stability improvement. The controller parameters used to improve the step response as well as performance characteristics of BLDC Motor. Effective tuning of PID
... ng of PID controller parameters is the main criteria to improve the performance characteristics. The conventional methods need manual tuning of PID parameters i.e., trial and error method. Optimization method used to get optimal values of PID. Especially PSO algorithm used to tune and to get optimal gain values of PID iteratively to control the performance of BLDC motor. In this project, conventional PID controller parameters tuning method is compared with the proposed method and the results are obtained. The design and analysis of the PSO based PID controller is simulated using MATLAB. The results obtained from simulation show the significant improvement in performance of BLDC than the existing methods. The step response of conventional methods and PSO method are shown above. As shown in the step response of all methods, proposed PSO method has good performance characteristics. The settling time and rise time are reduced when compared with conventional methods. Thus by PSO based PID controller has more advantage for BLDC motor.
