英文摘要：

To reduce the conservatism of delay-range-dependent stability and H∞ performance criteria, a Lyapunov-Krasovskii function was developed and the improved integral-equality approach was introduced. Then a less conservative delay-range-dependent stability criterion for Markovian jump systems was proposed in terms of linear matrix inequalities, and a sufficient condition was derived from the H∞ performance. Numerical simulations demonstrate the efficiency of the proposed method.
