英文摘要：

A position servo controller based on sliding mode control for permanent magnet linear synchronous motors was proposed. According to the magnitude of reference position, system phase orbits were designed respectively. Two first -order sliding surface were selected to control velocity and to position accurately, which strengthened the system robustness. The control law was easy to implement in digital. The experimental results show that the system runs in accordance with the designed orbit and realize the quick ,accurate and non-overshoot positioning.
