T1 Controllability of Convex Processes JF SIAM Journal on Control and Optimization YR 1986 FD 1986-11 VO 24 IS 6 SP 1192 OP 1211 AB The purpose of this paper is to provide several characterizations of controllability of differential inclusions whose right-hand sides are convex processes. Convex processes are the set-valued maps whose graphs are convex cones; they are the set-valued analogues of linear operators. Such differential inclusions include linear systems where the controls range over a convex cone (and not only a vector space). The characteristic properties are couched in terms of invariant cones by convex processes, or eigenvalues of convex processes, or a rank condition. We also show that controllability is equivalent to observability of the adjoint inclusion. SN 0363-0129 LK https://pure.iiasa.ac.at/id/eprint/13647/
