Abstract :
In this paper, we develop a simple model reference adaptive control (MRAC) scheme for a class of multi-input- multi-output (MIMO) linear dynamic systems with unknown time-varying state delay which is also robust with respect to an external disturbance with unknown bound. A suitable Lyapunov-Krasovskii type functional with "virtual" gain is introduced to design the adaptation algorithms and to prove stability.
