Title:

Asymptotic behavior of risk-sensitive control problems

Abstract:

In this talk we describe the certainty-equivalent of the infinite horizon with discounted cost for the Linear-Quadratic-Gaussian (LQG) model. Existence of optimal solution is investigated as well as explicit formulas for the value function. This problem is related with the ergodic (average-cost per unit time) criterion, analyzing the asymptotic behavior when the discount factor vanishes. It is shown that under a suitable log-transformation, a functional of the risk-sensitive discounted cost converges to the risk-sensitive average cost. This is based on a joint work with Pedro Salazar.
