The robust control issue for uncertain nonlinear system is discussed by using the method of right coprime factorization.As it is difficult to obtain the inverse of the right factor due to the high nonlinearity,the proving of the Bezout identity becomes troublesome.Therefore,two sufficient conditions are derived to manage this problem with the nonlinear feedback system as well as that with the uncertain nonlinear feedback system under the definition of Lipschitz norm.A simulation of temperature control is given to demonstrate the validity of the proposed method.
