Improved Robust Stability Criteria for Uncertain Discrete-Time Lur’e Systems with Interval Time-Delay

摘要：

　　This paper is concerned with robust stability for uncertain discrete-time Lure systems with interval time-delay and sector bounded nonlinearity.By dividing the variation interval of the time delay into two subintervals and using a novel sum-inequality,some new delay-dependent robust stability criteria are derived in the form of linear matrix inequalities(LMIs)without using the general free-weighting matrix method.The criteria are less conservative and more efficiently calculative in computing the maximum allowed delay bounds(MADBs).Finally,two standard numerical examples are presented the effectiveness of the proposed approach.
