Abstract

In this work, an adaptive control problem is investigated for the nonlinear active suspension systems (ASSs) with stochastic disturbances and time delay. Also, in the suspension system, the nonlinearity of the springs and the dampers are considered. In order to be closer to the actual system, the external random disturbances are not neglected in this paper. It is worth mentioning that unknown time-varying delay is considered in this study to facilitate the treatment of transmission time delay. Based on Lyapunov theory and backstepping technique, the presented adaptive controller is able to ensure that all the signals in close-loop system are uniformly ultimately bounded in probability. Finally, the simulation results further illustrate the effectiveness of the proposed approach.
随机扰动未知时滞非线性悬架系统的自适应控制
本文研究了具有随机扰动和时滞的非线性主动悬架系统的自适应控制问题。此外,在悬架系统中,还考虑了弹簧和阻尼器的非线性。为了更接近实际系统,本文不忽略外部随机扰动。值得一提的是,本研究考虑了未知时变时延,以便于处理传输时延。基于李雅普诺夫理论和反推技术,所提出的自适应控制器能够确保闭环系统中的所有信号在概率上一致最终有界。最后,仿真结果进一步验证了该方法的有效性。
