基于离散事件触发通讯机制(DETCS,discrete event-triggered communication scheme),研究了执行器故障下不确定非线性网络化控制系统的鲁棒H∞保性能容错控制与通讯协同设计问题。引入DETCS,采用状态反馈控制策略,建立了闭环故障系统模型;结合Lyapunov稳定性理论及少保守性技术,得到了DETCS下使系统具有鲁棒H∞保性能容错控制的时滞/事件依赖的充分条件,提供控制器与事件触发权矩阵协同优化求解的方法,讨论了几种不同目标约束下鲁棒控制与DETCS的协同设计问题;通过仿真实例验证了所述方法的有效性。
Based on discrete event-triggered communication scheme (DETCS), the robust H∞ guaranteed fault-tolerant control and communication collaborative design for uncertain nonlinear networked control systems with actuator failures are investigated. The introduction of DETCS, the use of state feedback control strategy, the establishment of a closed-loop fault system model; combined Lyapunov stability theory and less conservative techniques, the DETCS to make the system has a robust H ∞ guaranteed fault-tolerant control of the delay / event-dependent Condition, the method of collaborative optimization of controller and event triggering matrix is provided. The problem of collaborative design of robust control and DETCS under different constraints is discussed. The simulation results show the effectiveness of the proposed method.
