| Abstract | ||
| This paper investigates the robust tracking and regulation control problems for discrete-time, switched piecewise linear hybrid systems affected by parameter variations. In particular, the main question addressed is related to the existence of a controller such that the closedloop system exhibits an attainable desired behavior under all possible parameter variation. Checking attainability and calculating the state space regions for which a robust control is assured despite the uncertainty is performed using a polyhedral approach. A model predictive control law derived from a quadratic cost function minimization is further examined as a simple and fast sub-optimal robust control. An application of the proposed technique to a two-tank benchmark is finally presented. | ||
