研究了一类控制系数未知且输出函数不可导的非线性系统的采样数据控制全局输出反馈镇定问题。利用技术引理给出了输出函数的扇形区域，并结合鲁棒状态稳定器和降阶采样观测器设计了采样控制器.通过仔细选择适当的采样周期，所提出的控制器保证了闭环系统的全局渐近稳定性。
This paper considers global output feedback stabilization via sampled‐data control for a general class of nonlinear systems, which admit unknown control coefficients and nonderivable output function. A sector region of the output function is given by utilizing a technical lemma, and a sampled‐data controller is designed by combining a robust state stabilizer and a reduced‐order sampled‐data observer. By carefully choosing an appropriate sampling period, the proposed controller guarantees the globally asymptotical stability of the closed‐loop systems.
