The problem of designing a piecewise linear dynamical controller of the piecewise H1 type for a piecewise afine system has been considered. This problem corresponds to a family of H1 controller design problems. It has been shown that this set of problems can be cast as a set of convex optimization problems subject to Linear Matrix Inequality constraints that are solvable efficiently using existing software. The closed loop, consisting of the proposed controller and the piecewise affine plant, is capable of command following; subject to limitations on the energy of the control signal. Conditions may be imposed that insure the continuity of the control input to the plant. Piecewise quadratic Lyapunov functions are used to analyze closed loop stability. Performance is verified through simulation.
