Abstract


In recent years , the nonlinear observer design problem has become one of the research topic of concern for many scholars , and achieved fruitful results but mostly state observer for Lipschitz nonlinear systems research studies have shown that , in many cases with already criterion the design Lipschitz nonlinear systems observer is unable to achieve asymptotically stable paper for a few different class of nonlinear systems were studied full dimension , dimensionality reduction and output with the nonlinear terms since adapt to the design of the observer . main findings are as follows : · the profession known parameters of the adaptive observer Quasi sided Lipschitz condition Lipschitz conditions instead of the usual full dimension of a class of nonlinear systems , dimension reduction adaptive observer design . · to improve the existing system , so the output with nonlinear term and designed its observer . · bounded unknown parameters of the adaptive observer case , the design of adaptive regulator to estimate the unknown parameters norm . sided Lipschitz condition instead of the usual Lipschitz conditions of full-dimensional nonlinear systems , dimensionality reduction adaptive observer design and use contemplated .
