车用永磁同步电机高性能弱磁控制策略
Flux-weakening Control Strategy for Permanent Magnet Synchronous Motor Used in Electric Vehicles with High Performance
摘要
Abstract
A flux-weakening control method for permanent magnet synchronous motor(PMSM)used in electric ve-hicles is put forward on the basis of current prediction to improve the dynamic performance in the flux-weakening region of PMSM.The voltage boundaiy problem in the flux-weakening region is analyzed in detail,and the stability problem under different voltage selection criteria is also introduced.On this basis,a dynamic overmodulation strategy considering the stability and dynamic characteristics is proposed.Furthermore,a model-based predictive current control algorithm is investigated,in which the advantages of fast dynamic response and manageable constraints help to improve the dynamic performance in the flux-weakening region while guaranteeing the stability.Finally,the effectiveness of the proposed al-gorithm was verified on a simulation platform and an experimental platform,respectively.关键词
