摘　　要：为提高采用PI转速调节器矢量控制调速系统的动静态性能,提出以积分自整定模糊控制作为矢量控制转速调节器,此调节器的比例系数不变,可根据转速偏差和偏差变化率来动态调节积分系数。在此基础上,建立了异步电机矢量控制模型。仿真结果表明:相对于采用PI转速调节器的矢量控制系统,积分自整定模糊矢量控制系统转速超调量小、调节时间短,可快速消除负载扰动引起转速偏差。In order to improve the static and dynamic performance of vector control speed regulation system with PI controller, a kind of integration self-adjusting fuzzy control was introduced in the vector control speed regulator system. The proportion factor of this controller is invariable, and the integral factor is adjusted according to the speed deviation and the deviation change rate. The model of asynchronous vector control system was established on this base. The simulation results show that： compared with PI speed regulating, the integration self-adjusting fuzzy control speed regulating can reduce speed overshoot and adjust time, accelerate the speed recovery after load torque disturbance.
