Limited by the structure of the permanent magnet synchronous linear motor PMSLM itself, if the adjustment of the control system’s parameters were unreasonable, the performances of the control system would fail to meet the requirements. Based on studying the mathematical model of the permanent magnet synchronous linear motor, this paper focused on analysis the current loop and the position-speed loop of the servo control system, and achieving the decoupling control by vector control method. This paper adapted to the PID control algorithm plus the velocity feed-forward, the acceleration feed-forward and the NOTCH servo filter. The reasonable regulation of the permanent magnet synchronous linear motor’s PID parameters made the permanent magnet synchronous linear motor to achieve the best results. The measured experimental data of the permanent magnet synchronous linear motor validated the feasibility of this method, and all of that could pave the way for the application of the control algorithms in the future.
