Abstract :
To improve dynamic quality of PMSM speed servo system, a novel reaching law is proposed, different from the conventional reaching law, the system state is used to restrain the chattering and improve the reaching rate. The novel reaching law is applied to the PMSM speed servo system; a novel sliding mode speed controller is designed to replace the traditional PI regulator. Simulations and experimental results show that the novel speed controller can improve steady, dynamic performances and robustness characteristics of speed servo system obviously.
