针对一类网络化T-S模糊系统，在混合触发方案和非匹配隶属度函数下，设计了基于弹性切换器的输出反馈控制器。为了提高网络带宽利用率，在状态观测器和控制器之间引入了基于周期采样和事件触发切换的混合触发方案。针对基于模糊控制器的控制器参数实现不准确的问题，构造了一种新型的混合触发T-S模糊模型。利用李雅普诺夫理论和线性矩阵不等式技术，建立了增广模糊系统的充分条件。此外，基于线性矩阵不等式的控制器增益的设计。最后，数值例子来证明所提出的方法的有效性。
In this paper, the resilient observer-based output feedback controller is designed for a class of networked T–S fuzzy systems under a hybrid-triggered scheme and mismatched membership functions. In order to improve network bandwidth utilization, a hybrid-triggered scheme is introduced between the state observer and the controller, which is based on a switching between periodic sampling and an event-triggered scheme. Considering the inaccurate implementation of the parameters of the observer-based controller, a novel hybrid-triggered T–S fuzzy model is constructed. Sufficient conditions are established for the augmented fuzzy systems by using Lyapunov theory and the linear matrix inequality techniques. Furthermore, the observer-based controller gains are designed in terms of linear matrix inequalities. Finally, a numerical example is provided to demonstrate the usefulness of the proposed method.
