Optimal L1 control for linear time-delayed systems using GSA algorithm

In this paper a new optimal feedback design method for time-delay systems is developed. The proposed approach is based on the L₁ small-gain stability theorems and is applicable to systems with time varying delays. The proposed approach results lower degree controller compare to classical methods. The Gravitational search algorithm (GSA) is utilized for designing the controller parameters and the simulation results are presented to show the proficiency of the proposed method.
