| Abstract: | In this paper, a class of uncertain systems is considered which not only have the parameter uncertainty, but also contain an unmodeled feedback. In regard to the robust stability of the above systems, a result like Kharitonov' s four -polynomial theorem has been given by [1]. As the main result of this paper, then the above result is extended into the handling of a more general case. At the same time, this paper also approaches ways of judging the robust stability of systems with transfer function whose numeritor and denominator may be dependent or independent. Computation reveals that the results from the two cases are obviously different. |
