Abstract

This paper is concerned with the nonfragile H_∞ controller design problem for linear time-invariant systems. The controller to be designed is assumed to have norm-bounded uncertainties. Design methods are presented for dynamic output (measurement) feedback. The designed controllers with uncertainty (i.e. nonfragile controllers) are such that the closed-loop system is quadratically stable and has an H_∞ disturbance attenuation bound. Furthermore, these robust controllers degenerate to the standard H_∞ output feedback control designs, when the controller uncertainties are set to zero.
