摘要
Global asymptotic stabilization of nominally linear uncertain systems is considered where uncertain elements in the plant are modelled as cone bounded nonlinearities. At first, a linear time-invariant state feedback law ensuring global asymptotic closed-loop stability is obtained. The algorithm which calculates such a feedback law is simple and straightforward. It does not involve repeated solutions of a parameter dependent algebraic Riccati or any such non-linear equations. Any state feed- back law thus developed can then be implemented via an observer specially designed to preserve the global asymptotic stability of the closed-loop system. © 1990 Taylor and Francis Group, LLC.
