Abstract

In this paper, an observer-based control problem for time-delayed systems is considered. Based on the separation principle, we can design the controller and the observer gains independently. Since the resultant criterion is not formulated as Linear Matrix Inequalities (LMIs), we propose a relaxation technique that leads to an LMI-like iteration algorithm. Numerical examples demonstrate the effectiveness of the designed method.
