Modeling and simulation of the brushless DC motor fuzzy-PI control system

Based on the principle and structure of the brushless DC motor(BLDCM),and analyzing the mathematic mode,a simulation model of BLDCM speed and current double loop control system is established in Matlab/Simulink by the modular design.The static and dynamic performances of BLDCM were simulated,and the reasonability and validity were testified by the coincidence of the simulation results and theory analysis.This model has the virtues of simpleness,understandability,modifying parameters easily,also suitable for verifying the reasonability of other control algorithms.
