In order to restrain the high pump voltage which is unfavorable to system operation produced during the braking process of electric armored vehicles, the pump voltage as a function of PWM duty cycle is obtained by analyzing the generation mechanism of pump-up voltage during the braking process , A new digital control method that can effectively suppress the pump-up voltage by controlling the PWM duty cycle is proposed.The method can effectively reduce the capacitance, reduce the size of the controller to a certain extent, and improve the performance and price of the controller The results of computer simulation and experimental results prove the correctness and feasibility of this numerical control method.
