模糊控制在异步电机直接转矩控制系统中的应用

为提高异步电机直接转矩控制系统的低速性能，本文中提出了一种模糊控制和PI闭环校正磁链观测器相结合的控制方法。该方法采用PI闭环校正磁链观测器代替传统U-I模型，给磁链和转矩误差分级，用模糊控制代替传统滞环控制选择合适的电压矢量．为减少模糊控制规则和加快模糊推理，定义了定子磁链角映射。仿真结果表明，此方法能够提高磁链的观...

Fuzzy Direct Torque Control of Induction Motor

To improve the low-speed performance of direct torque control(DTC) of induce motor,this paper introduce a method which is combines fuzzy control with PI close-loop flux observer.This method used PI close-loop flux observer replaced the conventional UI model,divide flux error and torque error into different intervals and give different control voltages which generate by fuzzy controller instead of traditional hysteresis controller for each of them.A stator flux angle mapping technique has been proposed to re...
