摘要:研究了一类非线性部分满足Lipschitz条件的非线性不确定系统的鲁棒滑模观测器的设计问题。提出了一种将Thau观测器与Walcott-Zak观测器结合的非线性鲁棒滑模状态观测器设计方案,并利用Lyapunov定理证明了状态观测误差最后一致收敛于一个紧集。将所设计的滑模观测器应用于故障检测,仿真实验结果验证了该方法的有效性。
The design problem of robust sliding mode observer for a class of nonlinear uncertain systems satisfying Lipschitz condition is considered,and a new nonlinear robust sliding mode observer design method is proposed by combining Thau observer with Walcott-Zak observer.By means of Lyapunov theory,it is shown that the estimation error will uniformly ultimately converge to a bounded set.Moreover,the designed observer is applied to the fault detection.Finally,the effectiveness of the proposed method is further demonstrated via numerical simulation.
