The invention provides a self-adaptive fixed time event triggering fuzzy control method for an active vehicle suspension system. The method comprises the steps of acquiring state data of the active vehicle suspension system; and inputting the obtained state data into a preset event-based self-adaptive fuzzy control model, and controlling the active vehicle suspension to track a given track in real time according to the output control quantity. In the fixed time, all signals of the active vehicle suspension system are semi-globally consistent and finally bounded, and the vertical displacement of a vehicle body is limited in an upper boundary and a lower boundary which change along with time. The control strategy provided by the invention is irrelevant to the initial state information, convergence performance in fixed time is achieved, and limited communication resources of the active vehicle suspension system are saved. Time-varying displacement constraints can be ensured in the active vehicle suspension system to increase driving comfort for passengers.

    本公开提供了一种主动车辆悬架系统自适应固定时间事件触发模糊控制方法,获取主动车辆悬架系统的状态数据;将获取的状态数据输入到预设的基于事件的自适应模糊控制模型中,根据输出的控制量控制主动车辆悬架实时跟踪给定轨迹;其中,在固定时间中,主动车辆悬架系统的所有信号均为半全局一致最终有界,且车身垂直位移限制在随时间变化的上下边界内;本公开所述的控制策略与初始状态信息无关,实现了固定时间的收敛性能,节省了主动车辆悬架系统的有限通信资源;在主动车辆悬架系统中可以保证时变位移约束以增加乘客的驾驶舒适性。
