TY - JOUR VL - 45 SP - 1864 A1 - Bemporad, Alberto A1 - Ferrari-Trecate, Giancarlo A1 - Morari, Manfred PB - IEEE JF - IEEE Transactions on Automatic Control IS - 10 Y1 - 2000/10// EP - 1876 ID - eprints446 N2 - We prove, in a constructive way, the equivalence between piecewise affine systems and a broad class of hybrid systems described by interacting linear dynamics, automata, and propositional logic. By focusing our investigation on the former class, we show through counterexamples that observability and controllability properties cannot be easily deduced from those of the component linear subsystems. Instead, we propose practical numerical tests based on mixed-integer linear programming.
