Abstract :
Robust optimal (or perfect) model matching problem for the linear time-variant systems is dealt with in this paper. A two-degree of freedom controller is used. For the case of the nonminimum phase plants with multiplicative perturbations, the problem of robust stability of closed-loop system under the conditions of optimal model matching is transferred into a constrained H∞ optimization problem. A new method for determining parameters of the controller is given, which involves solving an H∞ interpolation problem
