摘　　要：永磁同步电机(PMSM)是一个多变量强耦合非线性系统,对外部扰动和内部参数变化较为敏感。传统PI调节器由于控制方法简单,被广泛应用于PMSM调速系统,但它往往不能满足高性能控制要求。为此,将滑模变结构控制(SMC)应用于PMSM调速系统,采用全局快速终端滑模(GFTSM)控制策略,给出了控制器的设计方法,并对比传统PI控制方法进行仿真分析。结果表明,相对于PI调节,该控制策略使系统具有响应快、稳定性好、超调量小以及抗负载扰动强等优点,提高了系统的鲁棒性。The permanent magnet synchronous motor （PMSM） is a widely used nonlinear multi-variable cou- pled system. It is sensitive to the load disturbance and the change of interior parameter. Traditional PI con- troller is widely used in the speed control of PMSM for its simplicity, but it cant meet the need of high per- formance. Therefore, gave the application of sliding mode control （SMC） in PMSM speed control system, u- sing a kind of control strategy named global fast terminal sliding mode （ GFTSM）, gave the design method of the controller, and had a simulation analysis after compared with traditional P! control method. The results demonstrate that compared with PI adjustment, the system has the advantages of fastness rapid response, sta- bility, robustness, no over-shoot and rejecting load disturbance.
