Abstract：The intelligent contactor based on current closed loop control is commonly accepted. In order to solve the disability of mechanical disturbance-resistant and beat delay problem, the active disturbance rejection with current model predictive control strategy is proposed. The mechanism of disturbance to current closed loop is analyzed. The current slope is observed under different coil voltage and core velocity. The anomaly of current rising slope related to iron core speed is proved to infer the motion of iron core under zero coil voltage. The deadbeat model considering induct electric potential compensation is established to predict current and eliminate control delay. The quadratic evaluation function for rolling optimization is introduced to predict optimum duty and switch function. The switch function of zero voltage is automatically set to observe current slope when disturbance happens. The current setpoint is adjusted autonomously and the contactor has the function of active disturbance rejection. Besides diminution of current static error, ripple and harmonic are considered when holding. Related simulation and experiment prove the effectiveness of the proposed strategy. The strategy particularly improve the holding stability of intelligent contactor used in new energy sector.
