摘　　要：针对基于Round-Robin通信协议网络化控制系统的鲁棒故障检测问题,考虑传感器饱和以及外部干扰,提出了一种通信协议约束下故障检测滤波器的设计方法.利用李亚谱诺夫稳定性理论和线性矩阵不等式技术得到故障检测滤波器存在的充分条件,通过求解具有凸约束的优化问题得到最优滤波器参数.所设计的故障检测滤波器不仅能够确保滤波误差系统均方渐进稳定且有较强的扰动抑制能力.通过数值仿真和DTS200三容水箱液体渗漏检测实验验证了该方法的有效性.To address the problem of robust fault detection for networked control systems with Round-Robin protocol in which the sensor saturation and external disturbance are concerned, we propose an approach for designing a fault detection filter under the constraint of communication protocol. The sufficient condition for the existence of the fault detection filter is derived by applying Lyapunov stability theory and linear matrix inequality technique, and the corresponding optimal filter parameters can be obtained by solving a convex optimization problem. The designed filter not only ensures the asymptotically mean square stability of the filtering error system but possesses a much better disturbance-restraint ability. The effectiveness of the proposed method is verified by a numerical simulation and a DTS200 three-tank leakage detection test.
