【Abstract】 The conditions for delay dependent asymptotic stability are given for the single time delay system by applying Lyapunov approach and structuring a parameter dependent Lyapunov function and using the property of matrix characteristic value and matrix norm, and the results obtained for the single time delay system are extended to the uncertain multiple time delay system. The relevant algorithms of "stratified recursive" are presented such that the conditions obtained are easy to realize and the feasiblity of the algorithms obtained is illustrated by an example.更多还原
