A geometric approach to robust performance of parametric uncertain systems
Jorge Bondía, Jesús Picó · International Journal of Robust and Nonlinear Control · 2003
Abstract A new approach for the robust performance problem for parametric uncertain systems is presented. Contrary to the classical approach, where specifications must be given in the frequency domain, this approach allows to deal with classical time specifications such as bounds on the overshoot, settling time and steady state error, which are matched to an uncertain reference model. Controller synthesis is then formulated as a set inclusion problem with a clear geometrical interpretation. Copyright © 2003 John Wiley & Sons, Ltd.
