Abstract
As is well known, the central idea in the behavioral approach to control is the one of interconnection. This consists in the intersection of a given behavior to be controlled with a suitable controller-behavior, in order to obtain a desired (controlled) behavior. On the other hand, many relevant system properties, such as stabilizability, are defined in term of trajectory concatenation. Indeed, a 1D behavior B is said to be stabilizable if all its trajectories can be concatenated with trajectories that converge to zero; this definition can be generalized to the multidimensional case. Still at the level of trajectory concatenation, is the notion of set-controllability has been introduced: a behavior B is said to be set-controllable to a sub-behavior B* if its trajectories can be driven to B*in the sense that they can be concatenated with some trajectory in this sub-behavior. A natural question to pose is whether a stabilizable behavior is set controllable to a sub-behavior which is stable (in a sense to be made precise). The aim of this contribution is to study the relationship between the stabilizability of a multidimensional behavior B, its set-controllability to a stable behavior, and the possibility of stabilizing it by interconnection, i.e., of finding suitable controllers whose interconnection with B yields a stable behavior.
