摘要：根据三相异步电动机的数学模型和矢量控制的基本原理，分析研究了ACM的矢量控制系统。由于传统 PI 控制不能对参数时变问题及时调整，本文采用自适应模糊 PI 控制应用于异步电机的调速系统中。建立带转矩内环的转速、磁链闭环控制系统的仿真模型，并对传统的 PI 控制及自适应模糊 PI 控制进行比较和仿真。其仿真结果表明自适应模糊 PI 控制具有较好的适应性、鲁棒性和较高的精确性。

Abstract: According to the mathematical model of the threephase asynchronous motor and the theory of vector control, analysed and researched the vector control system of the asynchronous motor. Because the traditional PI controller can not adjust the variable parameters in time , adaptive fuzzy PI controller was applied to the speed control system of asynchronous motor in this paper. Set up the speed and flux closedloop control system simulation model with a innerloop torque, based on the simulation model, traditional PI controller and adaptive fuzzy PI controller were compared and simulated. The simulation results show that the adaptive fuzzy PI controller has good adaptability , robustness and higher accuracy.
