| 摘 要： | 基于状态观测器的方法研究了一类具有非线性扰动的多重状态时滞系统的鲁棒故障检测问题，应用RBF神经网络逼近系统的非线性扰动，采用线性矩阵不等式(LMI)给出了与时滞上界相关的增益阵设计方法，并利用Lyapunov函数和一致有界引理证明了故障检测残差信号的一致有界稳定条件和对非线性扰动的鲁棒性，仿真示例说明了该方法的有效性。

| Abstract: | A robust RBF ANN-observer-based fault detection scheme is proposed for a class of multiple state (time-delay) systems with nonlinear perturbations. An LMI approach, connecting with upper bound of time-delays, is presented to design the observer gain-matrix. The uniform bounded stable condition of the residual and its (robustness) to nonlinear perturbations are proved by using Lyapunov function and uniform bounded lemma. (Numerical) simulation demonstrates the effectiveness of the proposed scheme. |
