Abstract

The admissible value interval for the Lagrange multiplier in robust H∞ output control is shown to be finite. Its bounds are determined and a computation procedure is designed to estimate the minimal external perturbation suppression level that can be attained in an uncertain system with unknown bounded parameters by a dynamic output controller.
