Abstract :
A static state-feedback controller is designed for a system that includes an uncertain input delay and a conically-bounded state-dependent perturbation. The ultimate goal is to robustly stabilize the system with respect to all allowed delays and perturbations. In addition, the design seeks to satisfy a 2-norm constraint in the control input. The technique is based on satisfying sufficient conditions expressed as linear matrix inequalities (LMI). A Lyapunov-Razumikhin approach is employed in the stability analysis to produce one set of LMI, while the input constraint introduces another group of LMI. The method yields an analytical expression for a state-feedback gain matrix that stabilizes the closed-loop system for all uncertainties and satisfies the input constraints
