Many adaptive and learning control problems can be formulated as optimization problems aiming at minimizing an objective function related to system performance: in this context, several research directions arise such as optimal control formulations for uncertain systems via the Bellman’s optimality principle, or solving the exploitation-exploration dilemma of controlling the system as well as possible based on current system knowledge (exploitation) or experimenting with the system so as to learn about its behavior and control it better in the future (exploration).
