This paper tackles the observer-based finite-time H control problem for networked nonlinear semi-Markovian jump systems (SMJSs) with actuator fault, parameter uncertainties and partly unknown transition rates via an improved dynamic event-triggered scheme (DETS). In comparison with traditional dynamic event-triggered scheme, the observer-based improved dynamic event-triggered scheme which is not restricted by real system states and could save more network resources is firstly proposed in this paper. Then, a more general actuator fault model is considered and the reliable observer-based state feedback controller is designed. Sufficient conditions are proposed to guarantee the closed-loop system is stochastically finite-time bounded with a prescribed H disturbance attenuation level. Lastly, two simulation examples are given to affirm the validity of the results obtained in this paper.

可靠的基于观察者的有限时间 H 执行器故障和参数不确定的网络非线性半马尔可夫跳跃系统的动态事件触发控制

本文解决了基于观察者的有限时间 H具有改进的动态事件触发方案(DETS)的具有执行器故障,参数不确定性和部分未知转换率的网络非线性半马氏跳跃系统(SMJS)的控制问题。与传统的动态事件触发方案相比,本文首先提出了一种基于观察者的改进的动态事件触发方案,该方案不受实际系统状态的限制,可以节省更多的网络资源。然后,考虑一个更通用的执行器故障模型,并设计了可靠的基于观察者的状态反馈控制器。提出了充分的条件以保证闭环系统随机地有一个规定的时间限制H干扰衰减水平。最后,给出了两个仿真例子,以验证本文结果的有效性。
