Abstract

The problem of uniformly bounded stability of a class of special uncertain nonlinear systems whose uncertain terms contain state, unmeasured state, control input and output is considered. When the unmeasured state is input state practical stability (ISPS), we can get a general result of the uniformly bounded stability of the systems through designing observer of the systems which gain can be obtained by a differential equation. We have also designed a dynamic output-feedback controller, and this feedback involves an on-line tuned gain.
