该文针对永磁直线同步电机的伺服控制,探讨了一种基于矢量控制逆变器和光栅尺的位置、速度伺服控制方案。速度调节器采用变结构PI控制算法,在消除静差的基础上,提高永磁直线同步电机的响应速度。位置调节器采用PD控制算法,使系统具有平稳、快速、无静差的跟随性能。仿真验证了其可行性,易于实际应用。

For permanent magnet tion and speed servo control based linear synchronous motor servo control, study on the design scheme of posion vector control inverter and grating ruler. The speed regulator adopts variable structure control of PI, on the basis of eliminating static error, improved the response speed of the permanent magnet linear synchronous motor. While the position regulator put to use PD control algorithm, made the following capacity of the system stable, fast, and no static errors. Simulation results prove the feasibility, and this method is easy to practical application.
