Abstract
In general, interval plants with a large uncertainty cannot be robustly stabilized by a linear, time-invariant controller. The solution presented in this paper is in terms of an overall nonlinear control law given by the connection of a linear, deterministic, time-varying compensator and of a supervisor. The compensator may assume a finite number of possible configurations, at least one of which stabilizes the plant. The task of the supervisor is that of determining the switching instants of a scanning among the elements of the family, according to a suitably defined experimental test on the output of the system. Bothe the deterministic and the stochastic cases are considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
