Abstract: A bus voltage control strategy of armored vehicle with electric transmission is proposed for the fluctuating voltage arising in the process of sudden acceleration and deacceleration. A small signal model including the super capacitor and motor loads is developed based on the topological structure of vehicular integrated power system of 8×8 armored vehicle. The causes of two kinds of bus voltage fluctuations are analyzed. A dual-channel compensation control strategy is proposed based on power feedforward control strategy and the negative impedance characteristics of motor loads. The effect of the control strategy is evaluated by hardware-in-loop simulation and prototype vehicle test. The results show that the bus voltage fluctuations caused by sudden acceleration and deceleration are well restrained by using power feedforward control strategy, but it has no influence on the voltage fluctuation caused by negative impedance characteristics. The bus voltage fluctuations are effectively restrained by the dual-channel compensation control strategy, which also improves the anti-interference ability of the system.
