  • Abstract
    The problem of robust stability and performance in feedback control systems with n real (possibly related) uncertain parameters and structured unmodeled dynamics (the latter taking the form of m complex blocks dynamic uncertainties) is considered. A robustness margin rm is defined with respect to such model uncertainty structure and an algorithm is developed to compute it. Robust stability and performance are characterized in terms of rm or the structured singular value μm. An iterative procedure using the above algorithm is given to compute tight bounds on km and μm . These bounds are exact for the case m⩽3
