【Abstract】 In this paper,the practical stability and the estimates of practical stability domains of some nonlinear dynamical system are discussed by Lyapunov function,some sufficient conditions of the existence of domain of practical stability are given,and the method of constructing practical stability domains of a kind of dynamical system are obtained,which improved the result in the proceeding literature.更多还原
