摘要：针对传统的永磁同步电机矢量控制算法中，采用常规PID控制器的速度环、电流环的双闭环控制方式会造成控制系统的动态性能不足，稳态效果不佳等问题。根据永磁同步电机的电流状态方程推导出电流预测控制模型代替电流环PID控制器。同时设计一种模糊PI控制器代替速度环PID控制器。实验结果表明，采用该算法的永磁同步电机调速系统具有更好的动静态性能，响应速度更快，抗干扰能力更强。

Abstract: With respect to problems arising in the management of permanent magnet synchronous motor vector, conventional PID controller with speed loop and current control loop.The doubleloop will cause less dynamic performance of the control system, the poor steadystate effects and other issues.Based on the permanent magnet synchronous motor current state equations derived, the current model predictive control in place of current loop PID controller, while designing a fuzzy PI controller displaced the speed loop PID controller. Experimental results show that the control system has better dynamic and static performance, faster response, antiinterference ability.
Key words: PMSM; current predictive control; fuzzy control
