磁悬浮轴承系统辨识与鲁棒控制
System Identification and Robust Control of Magnetic Suspension Bearing
摘要
Abstract
Regarding the complexity and dificulty in accurate modeling of magnetic suspension bearing rotor in the design of traditional robust controllers,the orthogonal polynomial fitting method is applied to measure the rigid body mode and systematically identify frequency response data of bending mode of the rotor through the modal experiment,and the controlled model of the magnetic suspension bearing rotor system is established.An H∞ robust controller is designed based on the controlled model of the maglev bearing established by system identification.The experimental results prove that the robust controller based on the system identification model can realize the stable suspension of the rotor and control the rigid body mode of the rotor.关键词
