摘　　要：本文从滑模变结构理论出发，结合智能控制，针对矢量控制的电主轴永磁同步电机伺服驱动系统设计了带负载转矩观测的模糊滑模变结构控制器。仿真结果表明该方案能使系统获得优良的动静态性能，对负载扰动具有很强的抑制能力，证明了模糊滑模变结构控制方法的合理和优越。Combining the theory of VSC with IC, a fuzzy and variable structure controller with the load torque observer is proposed in this paper for the servo driving system with vector control electrical spindle PMSM. The simulating result shows that the systern has good dynamic and statlc property and strong antidis-turbing ability against load disturbances,which demonstrates the reasonableness and the superiority of the fuzzy and variable structure control.
