In this paper, a control system is designed for a vehicle active suspension system. In particular, a novel terminal sliding-mode-based fault-tolerant control strategy is presented for the control problem of a nonlinear quarter-car suspension model in the presence of model uncertainties, unknown external disturbances, and actuator failures. The adaptation algorithms are introduced to obviate the need for prior information of the bounds of faults in actuators and uncertainties in the model of the active suspension system. The finite-time convergence of the closed-loop system trajectories is proved by Lyapunov's stability theorem under the suggested control method. Finally, detailed simulations are presented to demonstrate the efficacy and implementation of the developed control strategy.

基于终端滑模法的主动悬架系统自适应容错控制

在本文中，设计了一种用于车辆主动悬架系统的控制系统。特别是，针对存在模型不确定性、未知外部扰动和执行器故障的非线性四分之一汽车悬架模型的控制问题，提出了一种新的基于终端滑模的容错控制策略。引入自适应算法是为了避免对执行器故障范围的先验信息和主动悬架系统模型中的不确定性的需求。在建议的控制方法下，闭环系统轨迹的有限时间收敛性由李雅普诺夫稳定性定理证明。最后，给出了详细的模拟来证明所开发的控制策略的有效性和实施。
