The invention discloses an active suspension sliding mode control method and system based on event triggering and a medium. The invention mainly aims to solve the technical problems of network time delay, limited communication resources and output uncertainty of an actuator in an active suspension system. The method comprises the following steps: firstly, considering the uncertainty of sprung mass and actuator output in a suspension system, and establishing a 1/4 vehicle active suspension fuzzy model; then, an event triggering mechanism is established, and event triggering conditions are given; and finally, designing an active suspension sliding mode controller based on event triggering. According to the sliding mode control method, the problem of output uncertainty of the actuator is effectively solved, and the control effect is improved. Meanwhile, necessary data are only transmitted in a communication network through an event triggering mechanism, so that the problems of network time delay and communication resource constraint are effectively solved while the control effect is ensured, and the system communication pressure is greatly relieved.

    本发明公开一种基于事件触发的主动悬架滑模控制方法、系统和介质。本发明主要是解决主动悬架系统中存在网络时滞、通信资源有限以及执行器输出不确定性的技术问题。所述方法包括:首先,本发明考虑到悬架系统中簧载质量以及执行器输出存在不确定性,建立了四分之一车辆主动悬架模糊模型。接着,建立了事件触发机制给出事件触发条件。最后,设计了基于事件触发的主动悬架滑模控制器。本发明通过滑模控制方法有效处理了执行器输出不确定性问题,提升了控制效果。同时,通过事件触发机制仅在通信网络中传输必要的数据,从而实现保证控制效果的同时有效的解决网络时滞和通信资源约束的问题,大幅缓解了系统通信压力。
