A novel characterization of bumpless transfer among alternative controllers, both in continuous and discrete time, is introduced. The bumpless transfer problem is to design a compensation scheme guaranteeing an L2 (respectively, l2) bound on the mismatch, after the switching time between the actual plant output and a particular target, ideal response. Minimization of the gain from initial plant state mismatch to L2 (respectively, l2) plant output mismatch provides improved transients. A solution to the bumpless transfer problem is given, both for plants without input saturation and for plants with input saturation. The solution guarantees anti-windup features in the latter case.

Abstract
A novel characterization of bumpless transfer among alternative controllers, both in continuous and discrete time, is introduced. The bumpless transfer problem is to design a compensation scheme guaranteeing an L2 (respectively, l2) bound on the mismatch, after the switching time between the actual plant output and a particular target, ideal response. Minimization of the gain from initial plant state mismatch to L2 (respectively, l2) plant output mismatch provides improved transients. A solution to the bumpless transfer problem is given, both for plants without input saturation and for plants with input saturation. The solution guarantees anti-windup features in the latter case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
