摘要
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.
