Abstract  

In order to improve the dynamic response performance and the robustness of permanent magnet synchronous linear motor(PMSLM) control system, a novel model free current control method is proposed to solve the control instability caused by the parameter uncertainty in the traditional PID control method of PMSLM drives. Firstly, based on the super local model, the model free current controller of the PMSLM control system is designed. Secondly, the simulation model of PMSLM with PID controller and the model-free current controller are built, compared the output of simulation and experiment under the steady-state operation,the load mutation and the parameter change of motor. The results show that the proposed method improves the dynamic response performance of PMSLM control system and is robust to the uncertainty of motor parameters.

Key wordsPermanent magnet synchronous linear motor(PMSLM)      ultra-local model      model-free control      current control
