This paper considers the problem of sampled-data adaptive output feedback fuzzy stabilization for switched uncertain nonlinear systems associated with asynchronous switching. A state observer is designed to estimate the unmeasured states and fuzzy logic systems are employed to deal with the unknown nonlinear terms. Sampled-data controller and novel switched adaptive laws are constructed based on the recursive design method and an average dwell time constraint is given to ensure that the closed-loop system is stable. The proposed scheme is employed in a mass–spring–damper system to demonstrate its effectiveness.

具有异步切换的切换非线性系统的采样数据自适应输出反馈模糊稳定

本文考虑了与异步切换相关的切换不确定非线性系统的采样数据自适应输出反馈模糊镇定问题。状态观测器用于估计未测量的状态，并采用模糊逻辑系统来处理未知的非线性项。基于递归设计方法构建采样数据控制器和新颖的切换自适应律，并给出平均停留时间约束以确保闭环系统稳定。提议的方案用于质量-弹簧-阻尼器系统以证明其有效性。
