    摘要:

    本文研究了任意切换下互联切换非线性系统的输出反馈模糊自适应周期事件触发控制问题.模糊逻辑系统用于逼近未知非线性项.仅使用采样时刻输出构建状态观测器和模糊自适应律.为了减少通信资源的浪费,提出了一种周期事件触发控制器,该控制器仅利用事件触发的采样时刻信息.此外,所提出的离散时间事件触发机制仅在采样时刻进行间歇监测.最后,证明了闭环系统所有状态在任意切换下都是有界的,通过仿真结果验证了所提方案的有效性.

    Abstract:

    This paper investigates the problem of adaptive fuzzy periodic event-triggered control for output-feedback interconnected switched nonlinear systems under arbitrary switching. Fuzzy logic systems are employed to approximate the unknown nonlinear terms. A state observer and fuzzy adaptive laws are constructed by using only the sampled output information. To reduce the waste of communication results, a novel controller is developed that only uses the information at the event-triggered instants. Furthermore, the proposed discrete-time event-triggering mechanism performs intermittent monitoring at the sampling instants. It is finally proven that all states of the closed-loop system remain bounded under arbitrary switching, and the effectiveness of the proposed scheme is verified through simulation results.
