摘　　要：本文设计了一种二维模糊PID控制器作为SVPWM异步电机矢量控制系统的电流调节器,以改善这类系统电流的动稳态性能。基于对矢量控制中d、q轴电流响应性能的不同要求,论文给出了两种控制方案。仿真实验结果说明,电流环采用模糊PID控制器比采用常规的PI控制器具备更好的动稳态性能。In this paper, a kind of two-dimensional fuzzy PID controller is designed acted as current regulator of SVPWM asynchronous motor vector-controlled systems for the sake of improving the dynamic and steady state performance of current of this kind of system. Two kind of control schemes are proposed here according to the different requirements for current response performance of d and q axis in vector control. The simulation results show that the current regulator with fuzzy PID controller possesses better dynamic and steady state performance compared to counterpart of general PI controller.
