The invention discloses a composite electromagnetic suspension control system and a control method thereof. The control system comprises an electromagnetic actuator, a full-bridge circuit, a gating switch, a controllable DC/DC circuit, a rechargeable battery pack, a controller and the like, wherein the electromagnetic actuator is installed at the position of a damper of a traditional suspension system; a motor power line in the electromagnetic actuator is connected with the full-bridge circuit; a signal line of the motor is connected with the controller; the full-bridge circuit is connected with the adjustable power resistor, the controllable DC/DC circuit and the rechargeable battery pack through the gating switch; the output end of the controllable DC/DC circuit is connected with the rechargeable battery pack; a vehicle body posture data acquisition system is used for detecting vehicle body vibration information; and the controller is used for controlling the electromagnetic actuatorin combination with a control strategy according to the vehicle body posture and the vehicle body vibration information. The control method can adopt passive damping control, semi-active control andactive control. The fuel economy of the automobile or the energy utilization rate of the electric automobile can be improved.

    本发明公开了一种复合式电磁悬架的控制系统及其控制方法,该控制系统包括电磁作动器,全桥电路,选通开关,可控DC/DC电路,可充电电池组,以及控制器等;其中,电磁作动器安装在传统悬架系统的阻尼器位置,电磁作动器中的电机动力线与全桥电路相连,电机的信号线与控制器相连;全桥电路通过选通开关分别与可调功率电阻、可控DC/DC电路和可充电电池组相连,可控DC/DC电路的输出端与可充电电池组相连;车身姿态数据采集系统,用于检测车身振动信息;控制器则根据车身姿态和车身振动信息,结合控制策略对电磁作动器进行控制。该控制方法可以采用被动阻尼控制、半主动控制以及主动控制。本发明可以提高汽车的燃油经济性或电动汽车能量利用率。
