Abstract: The robust passive control problem for a class of time-varying uncertain singular systems with state-delay and input-delay was studied. The uncertainty is norm-bounded, but does not need to meet the matching condition. Based on LMI methods and the generalized Lyapunov function, the passive condition of time-varying delay uncertain singular systems was obtained. Furthermore, the design of a memoryless feedback controller was solved in terms of the solution of LMIs, making the closed-loop system strictly passive. Finally, a numerical example was simulated by utilizing Matlab LMI toolbox, and the result demonstrates the validity and effectiveness of the proposed method.
