Abstract.
We study the Lagrange Problem of Optimal Control with a functional \(\int_{a}^{b}L\left(t,\,x\left(t\right),\,u\left(t\right)\right)\,dt\) and control-affine dynamics \(\dot{x}\) = f(t,x) + g(t,x)u and (a priori) unconstrained control u∈ \bf R m . We obtain conditions under which the minimizing controls of the problem are bounded—a fact which is crucial for the applicability of many necessary optimality conditions, like, for example, the Pontryagin Maximum Principle. As a corollary we obtain conditions for the Lipschitzian regularity of minimizers of the Basic Problem of the Calculus of Variations and of the Problem of the Calculus of Variations with higher-order derivatives.
