Abstract
A linear parameter varying approach for designing a constant output feedback controller for a linear time-invariant system with uncertain parameters that achieves a minimum bound on either the H2 or the H∞ performance level is introduced. Assuming that the uncertain parameters reside in a given polytope a parameter dependent Lyapunov function is described which enables the derivation of the required constant gain via a solution of a set of linear matrix inequalities that correspond to the vertices of the uncertainty polytope.
