Abstract
The feedback law for a control problem with a nondifferentiable cost functional is characterized by an initial-value problem for a differential system with singular right-hand side. This system is characteristic for a partial differential equation formally satisfied by the feedback law. A regularization of the differential system and the partial differential equation is given, and the feedback laws for the smoothed problems are shown to converge to the original feedback law.
