Abstract: Consider stabilization and L2-gain control problems for Lur'e systems.For generalized plants described by Lur'e systems, to design state-feedback and dynamical output-feed- back controllers such that the closed-loop systems are absolutely stable and L2-gain finite, respectively. Solvable conditions are presented based on matrix inequility (MI) approach. Some feasible design algorithms are discussed.-
