The robust output feedback stabilization problem for a class of uncertain linear time‐delay systems containing a saturating actuator is studied in this paper. The systems are described by state differential equations with bounded time‐varying uncertain parameters and unknown constant delay in the state. New criterion for robust stabilizability of the uncertain time‐delay systems is presented and the corresponding observer‐based robust output feedback controller is derived in terms of the solutions of linear matrix inequalities (LMIs). Simulation results show that the obtained method is feasible.
