A new control synthesis approach is proposed for linear parametrically varying (LPV) systems using parameter-dependent quadratic Lyapunov functions. The synthesis problem is formulated via a set of linear matrix inequalities (LMIs). When solved, parameter-dependent controllers are obtained that stabilize the LPV systems and achieve guaranteed performance in an L/sub 2/-gain sense. The new approach includes the case of parameter-independent Lyapunov functions, and as a result provides additional flexibility in the control design.
