【Abstract】 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.更多还原
