| 摘 要： | 对于具有多变量、非线性、强耦合、慢时变等特征的异步电动机调速系统,实现定子磁链与电磁转矩的高精度动态解耦是提高系统性能的关键.首先通过非线性状态反馈建立感应电动机的α阶积分逆模型,并分析非线性状态反馈的误差对其逆模型精度的影响.在此基础上提出了一个基于主元分析神经网络补偿的感应电动机逆解耦控制方法,将补偿后的α阶积分逆...

| Abstract: | It is important to realize torque and stator flux dynamic decoupling control for induction motor(IM) drive,which is multi-input and multi-output,nonlinear and strong coupling system.First,an ?-order integral inverse model of IM is constructed by the nonlinear state feedback,and the reason that the inverse model accuracy is affected by the feedback error is deeply analyzed.On the base of this,an inverse decoupling control method for IM based on principal component analysis neural network(PCA-NN) compensation... |
