Using a delay decomposition method and linear matrix inequality （LMI） technique, the problems of asymptotic stability of descriptor systems with time-varying delay are studied. A new delay-dependent asymptotic stability criterion is presented to guarantee that the system is regular, impulse free and asymptotic stable. Furthermore, the maximum allowable upper bound （MAUB） on the admissible delay can be determined with the help of linear matrix inequalities toolbox in Matlab. Finally, an illustrative example is given to demon- strata the t^ff^ctiv^n~ nnA f,~=~;K;h, ,f tK .~ _~_1_~＇1~.
