This work investigates the observer-based asynchronous control of discrete-time nonlinear systems with network-induced communication constraints. To avoid the data collisions and side effects in a constrained communication channel, a novel dynamic event-based weighted try-once-discard (DEWTOD) protocol is proposed. In contrast to the existing protocols, the DEWTOD scheduling regulates whether the sampling instant to release and which node to transmit the sampling instant simultaneously. In light of a hidden Markov model, the time-varying detection probability matrix is characterized by a polytopic set. By resorting to the polytopic-structured Lyapunov functional, sufficient conditions are derived such that the closed-loop dynamic is mean-square exponentially stable, and the observer-based controller is designed. In the end, two numerical examples are provided to explicate the validity of the attained methodology.

采用基于动态事件的一次性尝试丢弃协议的非线性系统的基于观察者的异步控制


这项工作研究了具有网络引起的通信约束的离散时间非线性系统的基于观测器的异步控制。为了避免受限通信信道中的数据冲突和副作用，提出了一种新颖的基于动态事件的加权尝试一次丢弃（DEWTOD）协议。与现有协议相比，DEWTOD调度规定了是否释放采样时刻以及哪个节点同时传输采样时刻。根据隐马尔可夫模型，时变检测概率矩阵由多面体集来表征。利用多面结构李雅普诺夫泛函，推导了闭环动态均方指数稳定的充分条件，并设计了基于观测器的控制器。最后，提供了两个数值例子来说明所获得方法的有效性。
