永磁同步电机电流预测控制算法
A Predictive Current Control Scheme for Permanent Magnet Synchronous Motors
摘要
Abstract
This paper presented a discrete predictive current control scheme for permanent magnet synchronous motors（PMSM） based on the dead-beat algorithm in the synchronous frame to improve the performance of the current loop.Based on the mathematical model of PMSM,the current controller directly calculated the expected voltage vector according to the current reference and feedback values;then transformed the voltage vector into switch signals with space vector pulse width modulation model.The robust predictive current control was introduced to decrease the sensitivity of system stability caused by the model parameters error.Simulation and experiment results showed that the PMSM current predictive control scheme efficiently improved both the dynamic performance and the steady-state precision of the current loop.关键词
