Based on the advanced synchronous switching technology of ABB, this paper presented a model prediction control strategy that is used to suppress the bounce of a high voltage contactor. The purpose of this work is to control the bounce without changing any structure of a contactor. We focus on obtaining the dynamics equations of the contactor and analyzing the mathematical mechanism of its bounce by modeling motion orbits of the moving contact. The model predictive control(MPC) has been used to predict the m...
