Abstract: This paper introduces a new type of dynamic
programming PDEs for optimal control problems with performance criteria
involving curvilinear integrals. The main novel feature of the multitime
dynamic programming PDEs, relative to the standard Hamilton-Jacobi-Bellman
PDEs, is that they are connected to the multitime maximum principle. In
other words, we present an interesting and useful connection between the
multitime maximum principle and the multitime dynamic programming,
characterizing the optimal control by means of a PDEs system that may be
viewed as a feedback law. In the case of performance criteria involving
curvilinear integrals with quadratic integrands, the new equations lead to
multitime variants of the Riccati equation.
Section 1 shows how a multitime control dynamics determines the multitime
Hamilton-Jacobi-Bellman PDEs via the value function. Section 2 describes a
two-time dynamics with nine velocities. Section 3 describes the connection
between multitime dynamic programming and the multitime maximum principle.
Section 4 analyzes the linear regulator problems.
