Rotor Flux Linkage Identification Method of PMSM Based on Unscented Particle Filter
摘要
Abstract
Accurate identification of rotor flux linkage is an effective method to monitor the permanent magnet working condition of permanent magnet synchronous motor(PMSM),which guarantee the reliable running and realize high performance control of its drive system. The existing principal methods and their technical features for rotor flux linkage identification were first summarized,then,the real-time d,q axis inductance and correctional stator resistance were obtained based on frozen permeability method and PMSM operating temperature respectively,the rotor flux linage identification method of PMSM based on unscented particle filter(UPF)was proposed,and the simulation research and experiment validation of the proposed method were also implemented. The research results show that under some constraints of Gaussian and non-Gaussian noise environment,steady state and dynamic state operation condition of PMSM drive system,the proposed method always can realize accurate identification of rotor flux linkage with the consideration of d,q axis inductance and stator resistance variation of PMSM drive system,and the identification variance is relatively smaller.关键词
