| Abstract: | This paper focuses on the synthesis problem of robust and reliable stabilization for linear systems with norm bounded time varying parameter uncertainty in the state and delayed state matrices and also with actuator failures among a pre specified subset of actuators. LMI (linear matrix inequality) method is given for the memoryless state feedback synthesis problem to quadratically stabilize the given systems. The results depend on the size of the time delay via Lyapunov candidate with double integral. Finally, an example is given to illustrate the feasibility of the proposed method. |
