Partially asymptotically stable observer and finite-time observer for a class of chained systems were designed. The definition of partially asymptotically stable observer and finite-time observer for the chained systems were presen-ted.Then, the partially asymptotically stable observer and finite-time observer were constructed respectively.By theo-ries of homogeneity and Lyapunov stability, the asymptotical stability and finite-time stability of the observation errors were proved.At last, the validity of the method was demonstrated by a numerical example.
