| 摘 要： | 阐述开关磁阻电机驱动系统中取消位置传感器的理论依据,介绍一种基于模糊模型的转子位置检测方法。此方法以电流和磁链作为输入,用模糊算法运算得到转子的位置。为提高转子的精度,引入几种改进算法。前置滤波器用来检测和消除反馈信号中的噪声,自适应模糊参考系统用于优化电机模糊模型,位置预测模块则对转子位置进行修订。仿真分析证明,这种转子位置检测方法具有很高的精度。

| Abstract: | The measurement of rotor position for switched reluctance drive is essential to proper running.This paper introduces a method of detecting the rotor position based on fuzzy logic.In order to improve the measurement accuracy of the rotor position,some unique techniques are adopted.At first,the block of predictive filter is used to examine and eliminate the noise of the feedback signal.Then,an optimized fuzzy model of the motor is created using an Adaptive Neural Fuzzy Inference System(ANFIS).At last,the block of angle position selector can modify the rotor-position.The result of simulation indicates that the position obtained by this method is accurate for the operation of SRM. |
