On parameterized Lyapunov-Krasovskii functional techniques for investigating singular time-delay systems. (English) Zbl 1211.93067
Summary: The problem of robust stability of a singular time-delay system is investigated. A novel Lyapunov-Krasovskii Functional (LKF) is introduced which is a singular-type complete quadratic Lyapunov-Krasovskii functional with polynomial parameters. Stability conditions are derived in the form of linear matrix inequalities. Numerical examples are given to illustrate the effectiveness and lower conservatism of the new proposed stability criterion.
