摘要
电磁力非线性,转子的动态特性复杂性及模型参数不准确是电磁轴承控制器设计不可回避的问题.考虑了电磁轴承气隙、励磁电流、转速、温度对电磁力影响及转子动态性能复杂性和模型参数摄动,结合T-S模糊模型利于解决非线性特点及H∞鲁棒控制方法抑制扰动强鲁棒性特点,设计了H∞鲁棒-模糊电磁轴承控制器.实验表明:采用H∞鲁棒-模糊控制器,电磁轴承系统具有较好的动态性能和鲁棒性能,削弱了电磁力非线性、转子的动态特性及系统参数摄动对系统性能的影响.
It is considered that some key factors, such as effect of air gap, current, rotating speed, temperature, complexity of rotor dynamic performance and disturbance of model coefficients, affect the electromagnetic force. Because a TS fuzzy model precedes solving nonlinear questions and the H∞ robust control method is effective in sustaining outside disturbance, a H∞ robust and fuzzy controller of AMB is formulated. Following actual experiments with the above controller, it behaves with better dynamic performance and robustness than ever.
