Abstract

Abstract: Based on the analysis of the mathematical model of brushless direct current motor (BLDCM), a novel method for modeling of BLDCM was proposed. In MATLAB, the model of BLDCM was established by C MEX S-function, and the simulation results showed that the proposed method can enhance the simulation efficiency. Based on the modeling and simulation of BLDCM, a modification function was introduced and a self-turning fuzzy controller was built. According to the error and error rate of speed, the proposed modification function performed real-time regulation of fuzzy rules. There were six regulation parameters in the self-turning fuzzy controller, and these parameters could be optimized off-line by the genetic algorithm toolbox of MATLAB. Besides, a contrast simulation was performed among digital PI controller, basic fuzzy controller and the self-turning fuzzy controller with the optimized parameters, and simulation results indicateed that the last controller can provide the best control effect.
