Global Stabilization via Output-Feedback for High-Order Uncertain Nonlinear Systems

摘要：

　　This paper is devoted to the global stabilization via output-feedback for a class of high-order uncertain time-varying nonlinear systems.Mainly due to the time-varying control coefficients and the unknown time-varying growth,the problem has not yet been solved.By introducing time-varying transformation and observer,and skillfully employing adding a power integrator,time-varying technique and certainty equivalence principle,a time-varying output-feedback control design scheme is developed.It is shown that,with the appropriate choice of the design functions,all the signals of the closed-loop system are globally bounded,and furthermore converge to zero.It is worth mentioning that,in this paper,the serious system unknowns are effectively tackled by time-varying technique,rather than by adaptive technique as in most existing literature.
