Abstract
The appearance of touch points in state-constrained optimal control pr oblems with general vector-valued control is studied. Under the assump tion that the Hamiltonian is regular, touch points for first-order sta te inequalities are shown to exist only under very special conditions. In many cases of practical importance these conditions can be used to exclude touch points a priori without solving an optimal control prob lem. The results are demonstrated on a simple example.
