TY - CHAP N2 - We prove, in a constructive way, the equivalence between hybrid and piecewise affine systems. By focusing our investigation on the latter class, we show through counter-examples 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 M1 - 4 Y1 - 1999/// SN - 0-7803-5250-5 UR - http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=827980&isnumber=17968 KW - hybrid systems; mixed-integer linear programming; piecewise affine systems; controllability; integer programming; linear programming; linear systems; observability AV - none TI - Observability and controllability of piecewise affine and hybrid systems ID - eprints611 CY - Phoenix, Arizona SP - 3966 T2 - Decision and Control Conference A1 - Bemporad, Alberto A1 - Ferrari-Trecate, Giancarlo A1 - Morari, Manfred EP - 3971 PB - IEEE ER -
