The Research of Permanent Magnet Synchronous Motor Predictive Current Control Algorithm

Abstract:

To enhance the current regulation capability for PMSM when transient state, which caused by the existence of numerical delay such as current sampling and Pulse-Width Modulation (PWM) duty-cycle updating, this paper proposed a predictive current control algorithm for permanent magnet synchronous motor which based on deadbeat control. The numerical delays in conventional FOC system are eliminated in theory. Simulation and experiment results show that the PMSM (Permanent Magnet Synchronous Motor) current predictive control scheme improves both the dynamic performance and steady-state precision of the PMSM control system.
