Abstract

We consider the control system

$$\dot x = Ax + Bu,$$

subject to the state-dependent control restraint

$$u(t) \in \Omega \cap (\mathcal{H}{\text{ + }}Cx(t)\} ,$$

where Ω is a compact convex set, ℋ is a subspace, andC is a matrix. The existence of time-optimal maximal controls is proven. A natural application of this result is in solving time-optimal problems under the control restraintu(t)∈Ω and the requirement that the outputy=Sx be maintained at zero during the transfer, whereS is a given matrix. An example is provided.
