分析了永磁同步电机(PMSM)矢量控制系统的工作原理，针对传统PI控制器调节时间长、对电机参数依赖度高的缺点，采用了单步模型算法控制策略。设计了基于单步模型算法的永磁同步电机矢量控制系统，并进行了仿真分析。仿真结果表明，单步模型算法控制策略具有不过分依赖电机数学模型、能较好地抑制各种不确定性干扰等优点，系统在动态过程中有较小的超调，且对于负载扰动具有较强的鲁棒性。

The working principle of permanent magnet synchronous motor (PMSM) vector control system is analyzed. For the disadvantages of traditional PI regulator, like the long regulation time and high degree of dependence on motor parameters, a strategy of single step model algorithm is used. A PMSM vector control system based on single step model algorithm is designed, and the system is simulated and analyzed. The simulation results demonstrate that the single step model algorithm control has advantages of low dependence of motor mathematical model, less influenced by uncertainties. In the dynamic process, the system has a better rapidity of dynamic response and a smaller overshoot, and has strong robustness to load disturbance.
