A model-free predictive current control algorithm for interior permanent magnet synchronous(IPMSM)motor control system is proposed in this paper,which can improve the stator current tracking response ability.The algorithm does not depend on the motor model,such as stator resistance,inductance.The stator current is measured twice in a sampling period,according to the detected stator current and current difference.The stator current can be predicted by a simple operation.The simulation model of vector control system based on id=0 for IPMSM was built in MATLAB/simulink.The model-based and model-free predictive current control algorithms are verified respectively.The simulation results show that the system which adopted proposed algorithm has good current tracking response ability both in transient state and steady state.
