This is a category with all control problems that seek periodic solutions, i.e., a condition of the kind

$\Gamma[x] = P(x(t_f)) - x(t_0) = 0,$

has to hold. $P(\cdot)$ is an operation that allows, e.g., for a perturbation of states, such as needed for the formulation of Simulated moving bed processes, or for offsets of angles by a multiple of $2 \pi$ such as in periodic car driving.
