Aiming at the weakness that traditional PID controller can't adjust themselves according to parameter variation of BLDCM, based on the mathematical model of the brushless DC motor, a control strategy which is based on Radial Basis Function Neural Network is provided for BLDCM control system. The experiment result which is based on the environment of Matlab/Simulink show that this control strategy has better dynamic and static characteristics than traditional PID control strategy, reducing the steadystate error of the system and improve the adaptive capacity and anti-jamming, meet performance requirements.
