This paper is concerned with the nonfragile 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 disturbance attenuation bound. Furthermore, these robust controllers degenerate to the standard output feedback control designs, when the controller uncertainties are set to zero.
