Thrust Observer-Based Sliding Mode Variable Structure Control for Linear AC Servo System

Sun Yibiao Guo Qingding Shi Limei(Shenyang Polytechnic University)  
A novel variable structure control ( VSC) method with sliding mode for a linear direct - drive AC servo system is presented . The chattering of the VSC system is effectively minimised by designing a load thrust observer and disturbance feed forward compensation. The chattering can be disminished furtherly by an integral action in the sliding mode . Simulations and experiments verify that the proposed control scheme not only solve the thrust ripple problem of linear permanent - magnet synchronous motor ( LPMSM ) , but also make the direct - drive system have strong robustness to parameter variations and external disturbances.
