The present results deal with the stabilization of linear delay systems. Stabilizing control laws proposed are of discontinuous type and constitute the main contribution of the paper. A "toolbox" used in the control synthesis is based on conversion of a state representation to a regular form and on a new delay-dependent stability criterion. Different discontinuous unit controllers ensuring the global asymptotic stability are developed. By using an appropriate Lyapunov-Krasovskii functional, the control algorithms are proven to be robust with respect to matching disturbances with apriori-known upperbounds. Also, admissible upperbounds for the delay is derived. The study is supported by an example.
