| Abstract: | The shortage of the traditional PI control theory used in the output torque balance control of several brushless DC motors was pointed out.The model of the BLDCM was set up,and the state equation was given.Based on the model,the algorithm of variable structure sliding mode control(VSSMC) was used to keep the torque balance of two brushless DC motors.The sliding surface and the variable structure control law were designed,and the stability of the system was analyzed.This method was proved to be effective by simulation. |
