Abstract

This paper proposes the artificial intelligence (AI)-based optimal PID controller design optimization of brushless direct current (BLDC) motor speed control with phase advance approach. The proposed control system allows the speed adjustment of the BLDC motor by phase advance technique. In this paper, two selected AI algorithms, i.e., the adaptive tabu search (ATS) and the intensified current search (ICS) are conducted as the optimizer for the PID controller design. The proposed control system is simulated by MATLAB/SIMULINK. Results obtained by the ATS and ICS will be compared with those obtained by the Ziegler-Nichols (ZN) tuning rule and the genetic algorithm (GA). It shows that the speed response of the BLDC motor by phase advance with the PID controller optimized by the ICS outperforms better than the ZN, GA and ATS.

Summary

INTRODUCTION

The brushless direct current (BLDC) motor is a kind of synchronous motor having permanent magnets on the rotor and stator winding. The speed response of the BLDC motor system with phase advance can be done effectively by optimizing the values of PID controller parameter using artificial intelligence (AI) algorithms. The applications of AI algorithms for PID controller of the BLDC motor system with phase advance have not been presented in the previous researches [4], [8]-[11]. This paper presents the use of AI algorithms for tuning the PID parameters (KP, Ki and Kd) for controlling the BLDC motor with phase advance. Phase advance The phase advance technique is a common control of the phase current to lead the phase back emf It can increase the speed of BLDC motor over the base speed. The proposed drive system composes of three phase inverter, switch control signals, Hall effect sensors, BLDC motor and DC voltage source.
