This paper investigates the switching control issue for uncertain vehicle suspension systems, meanwhile, actuator failure is taken into account. Takagi-Sugeno (T-S) fuzzy model is utilized to describe the considered uncertain suspension systems. Consider that most existing analysis results related to suspension systems are independent of membership functions, which may cause conservatism, thus, a novel membership functions-dependent Lyapunov function is employed in the stability analysis. In the proposed analysis technique, both of the information of membership functions and their derivatives are applied to reduce the conservativeness. A switching control strategy is proposed to assure that suspension constraint requirements are satisfied by using the information of time-derivative of membership. Lastly, a simulation example is shown to identify the availability of the approach put forward in this paper.

本文研究了不确定的车辆悬架系统的切换控制问题，同时考虑了执行器故障。Takagi-Sugeno（TS）模糊模型用于描述考虑的不确定悬架系统。考虑到大多数与悬架系统有关的现有分析结果都与隶属函数无关，这可能会导致保守性，因此，在稳定性分析中采用了依赖于隶属函数的新型Lyapunov函数。在提出的分析技术中，隶属函数及其导数的信息都被应用以降低保守性。提出了一种切换控制策略，以通过使用成员时间导数信息来确保满足悬架约束要求。最后，
