This graduate course will aim to cover some of the fundamental probabilistic tools for the understanding of Stochastic Optimal Control problems, and give an overview of how these tools are applied in solving particular problems. In the literature, there are two types of MPCs for stochastic systems; Robust model predictive control and Stochastic Model Predictive Control (SMPC). book Noté /5. The purpose of this paper is to review some of these applications together with appropriate solution methodologies and also to discuss the latter in comparison with one another. again, for stochastic optimal control problems, where the objective functional (59) is to be minimized, the max operator app earing in (60) and (62) must be replaced by the min operator. presentation of these ideas will be a bit informal. Dynamic Programming • The basic idea. DOI: 10.1093/0199280576.001.0001. Since many of the important applications of Stochastic Control are in financial applications, we will concentrate on applications in this field. One of the salient features is that the book is highly multi-disciplinary. Download preview PDF. The control of a linear stochastic system with a Brownian motion and a quadratic cost functional in the state and the control is probably the most well known explicitly solvable stochastic control problem in continuous time. The theory of BSDEs has found wide applications in areas such as stochastic control, theoretical economics and mathematical finance problems. Sign in to YouTube.

Robust model predictive control is a more conservative method which considers the worst scenario in the optimization procedure. Stochastic control/optimization problems arise in various applications in finance where the control is usually given by an investment strategy. The course will roughly break into two parts: after Cite as. In a continuous time approach in a finance context, the state variable in the stochastic differential equation is usually wealth or net worth, and the controls are the shares placed at each time in the various assets. Karatzas Stochastic control is a classical topic in applied mathematics and occurs in many practical situations when we have to take decisions under uncertainty. These control problems are likely to be of finite time horizon.

In the first part of this thesis, we are interested in the pricing and hedging of European options. Consider the so-called reachability set ( … Costs (Curdin Ott, Lecture 8). stochastic control and optimal stopping problems. equations, diffusions and the Feynman-Kac formula, however the fundamental probabilistic tools for the understanding The value of a stochastic control problem is normally identical to the viscosity solution of a Hamilton-Jacobi-Bellman (HJB) equation or an HJB variational inequality. Stochastic control problems are widely used in macroeconomics (e.g., the study of real business cycle), microeconomics (e.g., utility maximization problem), and marketing (e.g., monopoly pricing of perishable assets). we will try to cover material quickly, and so the B. Øksendal (Oslo University) and A.Sulem have written a book on Stochastic control of Jump diffusions . These problems are moti-vated by the superhedging problem in nancial mathematics.

Øksendal's We study these problems within the game theoretic framework, and look for open-loop Nash equilibrium controls. The HJB equation corresponds to the case when the controls are bounded while the HJB variational inequality corresponds to the unbounded control case. pp 317-344 | • The martingale approach. However, this method, similar to other robust controls, deteriorates the overall controller's performance and also is applicable only for systems with bounded uncertainties.
