Delay-independent absolute stability for time-delay Lur'e systems with sector and slope restricted nonlinearities

摘要

This Letter presents an analysis method for a delay-independent absolute stability of time-delay Lur'e systems with sector and slope restrictions. The proposed method is based on the Lyapunov functions with quadratic form of states and nonlinear functions of the systems. Several criteria are derived in terms of linear matrix inequalities (LMIs). A numerical example is illustrated to show the effectiveness of the proposed method. (C) 2008 Elsevier B.V.
