摘　　要： 在当前三相永磁同步电机(PMSM)的控制,一般都是传统的PI控制,因为PI调节器的结构简单、可靠性高、参数简单、便于计算等优点,受到工业界广泛应用。但是,由于三相PMSM本身内部结构复杂,各个参数之间具有强耦合性,所以系统的抗外界干扰能力很差,传统的PI调节器并不能满足系统控制要求。而滑模控制,所具有的抗外界干扰能力强、响应速度快等优点,恰恰弥补了PI调节器的不足,在三相PMSM速度控制中能够具有更好的效果。 Generally, the control of recent three-phase PMSM is traditional PI control for its advantages of simple structure and parameter, high reliability and easy calculation. However, due to the complex inner structure of three-phase PMSM and strong coupling of each parameter, traditional PI regulator can＇ t meet systematic control demand for its low anti-interference capacity, for which sliding mode speed controller can make up with its advantages of strong anti-interference capacity and high response speed.
