Quadratic stabilization of LPV plant by output feedback

Linear time invariant output feedback controllers are considered to design for linear parameter varying plant with dependent parameters that are not measurable on-line, in order to make closed-loop system achieve quadratic stability. Here the dependent parameters are assumed to vary in a plant parameter space that is a polytope. Moreover, sufficient conditions of existence of such a controller are presented in terms of linear matrix inequalities (LMIs) formulation.
