Auto-disturbance-rejection control (ADRC) technology is nonlinear robust control technology. Its nonlinear feedback relies on the size and direction of the error between desired and the actual trajectory. When the controlled object is disturbed by uncertain factor or its parameters change, ADRC can transform nonlinear system into an integral series structure of linear system by using nonlinear transformation, what can realize feedback linearization of dynamic system and improve system’s control performance. According to above, we propose to apply ADRC technology to brushless DC motor control system to restrain torque ripple and improve system’s disturbance-rejection in this paper. After theoretical analysis the feasibility of this method, we made a simulation. Simulation results show that the effects of torque ripple suppression and anti disturbance ability of the system have been improved.
