Category:Periodic

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

has to hold. ${\displaystyle P(\cdot )}$ 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 ${\displaystyle 2\pi }$ such as in periodic car driving.
