Method to Reduce Position Measurement Error of Electromagnetic Bearings

ZHANG Qing-chun,JIANG Jun,LI Guo-dong,LIANG Ying-chun(School of Mechanical and Electrical Engineering,Harbin Institute of Technology,Harbin 150001,China)  
The performances of EMB system are directly affected by position measurement error.The weighting correction formula FKS3/5 of displacement measurement error is given by the least squares principle,in which the real time requirement is met in the dynamic measurement of the electromagnetic bearing system and the displacement measurement accuracy is increased.The results of the simulation analysis show that position measurement error in system can be decreased and the system dynamic performances are increased by the algorithm.
