本文研究具有事件触发传输机制的网络随机系统的耗散控制问题。与现有的一些结果不同的是，来自物理对象的信号是非均匀采样的。为了节省宝贵的通信资源，引入了一个数据包处理器，根据灵活的事件触发条件选择必要的数据包。通过建立随机环境下的积分不等式，将其作为基于Wirtinger的积分不等式的对应形式，得到了闭环系统均方稳定且耗散的判据。然后，该判据被用来根据线性矩阵不等式的解来计算合适的事件触发控制器。最后以某飞行器系统为例，验证了该方法的有效性。
This paper is concerned with dissipative control for networked stochastic systems with an event-triggered transmission mechanism. Different from some existing results, signals from a physical plant are samplednon-uniformly. In order to save precious communication resources, a data-packet processor is introduced to choose necessary data-packets based on a flexible event-triggered condition. By establishing an integral inequality in stochastic setting, which is regarded as a counterpart of Wirtinger-based inequality, a criterion is derived such that the resultant closed-loop system is mean-square stable and dissipative. This criterion is then used to calculate suitable event-triggered controllers in terms of solutions to linear matrix inequalities. An air vehicle system is finally taken to substantiate the validity of the proposed method.
