Abstract
Aiming at the deterioration of position control performance in the position servo system of permanent magnet synchronous motor(PMSM)due to internal and external disturbances such as load torque variation,an optimal position control method was proposed with anti-disturbance capability on the basis of active disturbance rejection control mechanism.First,a third-order nonlinear extended state observer was established to estimate the generalized disturbance and the original system was dynamically compensated according to the estimated value,which effectively improved the anti-disturbance ability of the position servo system.Then the controller was designed based on the idea of the fastest control synthesis function of the discrete second-order integral series system,which optimizes the dynamic performance of the position control in the servo system.Simulation results show that the proposed method can maintain the good position control performance when the motor parameters were perturbated or the load torque was suddenly applied.关键词
