This manuscript provides a theoretical foundation for the Dynamic Mode Decomposition (DMD) of control affine dynamical systems through vector valued reproducing kernel Hilbert spaces (RKHSs). Specifically, control Liouville operators and control occupation kernels are introduced to separate the drift dynamics from the control effectiveness components. Given a known feedback controller that is represented through a multiplication operator, a DMD analysis may be performed on the composition of these operators to make predictions concerning the system controlled by the feedback controller.
