Based on this property, a newsynthesis method-the Self--Stable Region approach is suggested for a class of second-ordernonlinear uncertain systems. The global stability of the closed-loop systems is proved.Lastly, the advantages of the SSR approach are analyzed.展开更多

Since ESO adopts the continuous non-smooth structure, the classical observer design theory is hard to use for ESO analysis. In this note, the self-stable region (SSR) approach, which is a nonlinear synthesis method for nonlinear uncertain systems, will be used for ESO design and its stability analysis. The advantages of the non-smooth structure in ESO for improving the convergence properties and the estimation precision will be shown.展开更多
