| Abstract: | In this paper, robust stabilization conditions based on theH ∞-norm are derived for multivariable feedback systems under perturbations and constrained control. The parametrized controller of Youlaet al. is employed to treat this problem. In addition, a necessary and sufficient condition is derived for the solvability of the synthesis problem for a controller which achieves robust stability. Finally, a design procedure is proposed for selecting the parameters of the robust controller, and an illustrative example is given. |
