Identification of the Magnetic Bearings Support Parameters Using an Extend Kalman Filter
摘要
Abstract
An identify measurement of stiffness and damping to AMB system is introduced.By ap-plying unbalance excitation to the rotor,stiffness and damping can be identified use extended Kalman filter (EKF ) algorithm.The simulation result shows that it is efficient for this method to measure the stiffness and damping of AMB.Then used the method to identify the supporting parameters in experiment and brought the identified results to simulate files to compare the displacement re-sponse.The results indicated that the EKF method can efficiently identify the stiffness and damping.关键词
