Vanishing Discount Limit and Nonexpansive Optimal Control and Differential Games

SIAM Journal on Control and Optimization, 2015
Summary: A classical problem in ergodic control consists of studying the limit behavior of the optimal value \(V_\lambda\) of a discounted cost functional with infinite horizon as the discount factor \(\lambda\) tends to zero. In the literature, this problem has been addressed under various conditions ensuring that the rescaled value function \(\lambda

Equivalences between differential games and optimal controls

Journal of Optimization Theory and Applications, 1976
It is shown that linear differential pursuit games with linear targets, if player controls are required to be piecewise constant or if player controls areL1-functions (but pursuer control is bang-bang whenever quarry control is), are equivalent to a linear, autonomous control problem.

A GRID REFINEMENT METHOD FOR DETERMINISTIC CONTROL AND DIFFERENTIAL GAMES

Mathematical Models and Methods in Applied Sciences, 1994
We develop here a simple method for the computation of value functions of deterministic optimal control or differential games problems which allows to refine locally a grid and reduce memory space. Given an approximation of optimal trajectories, one can solve the associated Hamilton-Jacobi equation in a tubular neighborhood with state-constraints ...

Risk sensitive optimal control and differential games

2007
Risk-sensitive stochastic control problems for nonlinear systems described by stochastic differential equations are considered. A logarithmic transformation is applied to the optimal cost function. The value function for a zero-sum, two-controller differential game is obtained in the limit, as a small parameter which represents noise intensity tends to

Singular Characteristics in Optimal Control and Differential Games

IFAC Proceedings Volumes, 1998
Abstract For arbitrary first order PDE the notion of singular characteristics is introduced, which, particularly, is related to Hamilton-Jacobi, Bellman-Isaacs equation in Optimal Control and Differential Games. Singular characteristics are effective for the construction of singular paths and surfaces.

Differential games, dynamic optimization, and generalized control theory

Journal of Optimization Theory and Applications, 1970
In this paper, we examine the problem of control in a generalized framework in which there are more than one criterion, more than one intelligent controller, each of which has access to different information. It is argued that optimal control, differential games, dynamic team theory, etc., can all be viewed as special cases of this generalized control ...
