Novel Stabilization Conditions for Uncertain Singular Systems with Time-Varying Delay

الملخص EN

The problem of delay-dependent robust stabilization for continuously singular time-varying delay systems with norm-bounded uncertainties is investigated in this paper.

First, based on some mathematical transform, the uncertain singular system is described in a form which involves the time-delay integral items.

Then, in terms of the delay-range-dependent Lyapunov functional and the LMI technique, the improved delay-dependent LMIs-based conditions are established for the uncertain singular systems with time-varying delay to be regular, causal, and stable.

Furthermore, by solving these LMIs, an explicit expression for the desired state feedback control law can be obtained; thus, the regularity, causality, and stability of the closed-loop system are guaranteed.

In the end, numerical examples are given to illustrate the effectiveness of the proposed methods.
