In this paper, we propose contributions on the stabilization and H8 control of switched linear systems subject to time-delays through the assignment of the switching law. As a first step, based on previous results related to switched linear systems with no time-delays and exploiting the concept of piecewise quadratic LyapunovKrasovskii functionals, we solve the problem of finding suitable state-dependent switching laws ensuring the prescribed control objectives. Secondly, we extend such results and present a strategy to construct an output feedback switching law, based on the available measurements made on the system. In both cases, the design of the control strategy is done by computing a feasible solution to a set of matrix inequalities associated to the modes of the switched linear system.
