Abstract :
The dynamic output feedback L2 disturbance attenuation control of linear parameter-varying (LPV) singular systems is investigated in this paper. Based on a general Lyapunov inequality, we first provide a condition that guarantees the admissability and the L2 gain performance of LPV singular systems. Then, the existence of dynamic output feedback L2 disturbance attenuation controller of the system is discussed. Finally, a dynamic output feedback controller is constructed by solving a coupled generalized algebraic Riccati inequalities. It is shown that the closed loop system is admissible and satisfies the desired L2 performance.
