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.
