For the performance of position servo system of three-phase permanent magnet AC synchronous motor is always influenced by the disturbance and changes in the parameters, the adaptive inverse control strategy will be applied to its precise position control. And for adaptive filtering algorithms to be improved,a novel variablestepsizelms adaptive filter algorithm is proposed for inverse model and model of the magnet synchronous servo motor position control system. The result shows that lmsalgorithm could resolve the contradiction among convergent speed, trace speed of the time-varying system and convergent accuracy. The position control system based on adaptive inverse control is robust to disturbance and the parametric variation of motor.
