It is a mathematical optimization technique commonly used in creating control policies. Optimal control theory is a branch of mathematical optimization that deals with finding a control for a dynamical system over a period of time such that an objective function is optimized. Optimal control theory has been very well developed in the past years out of the need to derive a control policy such that a certain optimality criterion is reached.
