Abstract

An observer-based dynamic surface controller (ODSC) for a class of nonlinear system is designed. Firstly, observer is designed with quasi-one-sided Lipschitz condition to reduce conservative, then, a DSC is designed based on the state estimation. The method can enable the independent design of the observer and DSC. The global robust stable is proved and the tracking errors are bounded. Finally, a SISO uncertain nonlinear system is simulated to test stability of ODSC later.
