This paper investigates the control of uncertain linear systems under the event-triggered control framework. The uncertainty is a mismatched type without known upper bounds. To reduce the redundant transmission of control signals, three triggering strategies are developed, namely, the absolute threshold triggering manner is built firstly to deal with the small control input variation. By revisiting the first one, the large control input is monitored by the second triggering scheme. Lastly, a trade-off between the above two triggering measures is made to cover all possible inputs without sacrificing system performance largely. Based on the proposed triggering strategies, different adaptive controllers containing the triggering threshold bound are constructed to eliminate the unknown uncertainty and ensure uniformly bounded with the required performance level, which is verified by simulation studies.

触发阈值相关方法控制不确定线性系统
本文调查了 事件触发控制框架下不确定线性系统的控制 不确定性是不匹配的类型,没有上限。为了减少控制信号的冗余传输,提出了三种触发策略,即首先建立绝对阈值触发方式来处理较小的控制输入变化。通过重新访问第一个,第二个触发方案将监视较大的控制输入。最后,在不影响系统性能的前提下,在上述两种触发措施之间进行权衡以涵盖所有可能的输入。基于提出的触发策略,构造包含触发阈值边界的不同自适应控制器,以消除未知的不确定性并确保与所需的边界均匀一致 性能水平,已通过仿真研究验证。
