Abstract: The problem of vibration and noise of the PMSM have been a difficult dilemma, it makes the system unstable and sometimes present the chaotic phenomenon. Advanced control method can depress vibration and noise and improve the control performance. the paper gives a design of global nonsingular terminal sliding mode controller for BLDC Motor which can makes the control system is insensitive to any disturbance. The simulation results prove the validity of the controller, and by compare with classic PID control, it has beed proved that the global nonsingular terminal sliding mode controller is more effective.

摘要：

永磁同步电机的振动和噪声一直是困扰人们的难题，严重时可能直接决定系统能否稳定运行，甚至会产生混沌现象。采用先进的控制算法，可以减弱振动和噪声，提高驱动性能。针对永磁无刷直流电机设计一种全局非奇异终端滑模控制器，该控制器可以控制控制系统对外界扰动完全免疫，从而使得电机在连续调速、负载波动的情况下具有平稳特性，与经典PID控制相比具有更强的鲁棒性。
