摘要:
针对一类同时存在未知干扰输入和传感器数据包丢失的网络控制系统,假定其可能发生故障,设计了鲁棒H∞状态观测器,对其进行故障检测。首先对此类网络控制系统进行了建模,建立了系统的状态观测器,并将该观测器误差方程等效为离散切换系统。然后基于李雅普诺夫稳定性理论,给出了观测器系统为鲁棒H∞状态观测器的充分条件及观测器增益矩阵的求解方法。为了增强鲁棒性和灵敏度,将阈值的选取归结为具有线性不等式约束的最小化问题。最后的仿真示例验证了文中方法的有效性。
Abstract:
Focusing on a class of networked control systems with unknown interference inputs and packet dropout in sensor data,the robust H∞ state observer is designed to detect them when faults occur in the system.A model and the state observer are constructed for the system,and the observer error equation is kept equivalent to the discrete switched system.Based on Lyapunov stability theory,the sufficient condition of the observer being a robust H∞ state observer and the method to find the observer gain matrix are both given.In order to enhance the robustness and sensitivity,the threshold is selected with solving the minimization problem involving a linear matrix inequality constraint.An illustrative example is given to demonstrate the effectiveness of the proposed method.
