【Abstract】 A cascaded slide mode control scheme is designed for permanent magnetic synchronous machine AC servo system. Integrate compensator is introduced in slide mode controller of velocity loop to reduce the torque chattering, and the pseudo slide mode control is used in place loop to reject the place chattering. Simulation shows that the scheme has strong ability of resisting parameter distortion and interference, exihibits good control performances.更多还原
