Abstract: The problem of designing robust non-fragile H∞ controller was studied for nonlinear uncertain time delay system with input delay.The integral controller was designed by the past states in the nonlinear uncertain system satisfying the gain bounded.It not only makes the closed-loop system asymptotically stable,but also makes H∞ norm not greater than a given index from the perturbation to the controlled output transfer function.And the criterion is the delay dependent.Finally,a numerical example sh...
