摘要: Abstract In this paper, the design of a PD controller for robust H ∞ stabilization uncertain Lur’e systems with sector and slope restricted nonlinearities is considered. A utilized to not only guarantee stability but also reduce effect external disturbance norm constraint. Sector bounds are used on Lyapunov–Krasovskii functional through convex representation nonlinear function so that less conservative criterion obtained. Using Finsler’s Lemma, derived in terms linear matrix inequalities (LMIs) can be easily solved by various optimization techniques. Several examples show effectiveness proposed methods.
