A Maximum Principle for Controlled Time-Symmetric Forward-Backward Doubly Stochastic Differential Equation with Initial-Terminal Sate Constraints

open access: yesAbstract and Applied Analysis, 2012
We study the optimal control problem of a controlled time-symmetric forward-backward doubly stochastic differential equation with initial-terminal state constraints. Applying the terminal perturbation method and Ekeland’s variation principle, a necessary

Probability-Weighted Optimal Control for Nonlinear Stochastic Vibrating Systems with Random Time Delay

open access: yesShock and Vibration, 2018
A probability-weighted optimal control strategy for nonlinear stochastic vibrating systems with random time delay is proposed. First, by modeling the random delay as a finite state Markov process, the optimal control problem is converted into the one of ...

Delayed Stochastic Linear-Quadratic Control Problem and Related Applications

open access: yesJournal of Applied Mathematics, 2012
We discuss a quadratic criterion optimal control problem for stochastic linear system with delay in both state and control variables. This problem will lead to a kind of generalized forward-backward stochastic differential equations (FBSDEs) with Itô’s ...

Assessing non-convex value functions for the optimal control of stochastic differential equations

open access: yesResults in Control and Optimization, 2022
Solving the optimal control of stochastic differential equations (SDEs) using the dynamic programming method requires writing the problem in terms of the so-called value function. This paper presents conditions to assure that the value function is convex
