The expected beam sizes for APS Upgrade are in the order of 4 microns for both planes. Orbit stabilization to 10% of the beam size with such small cross-sections requires pushing the state of the art in fast orbit feedback control, both in the spatial domain and in dynamical performance; the latter being the subject of this paper. In this paper, we begin to study possible performance benefits of moving beyond the classic PID regulator to more sophisticated methods in control theory that take advantage of a-priori knowledge of orbit motion spectra and system non-linearities. A reliable model is required for this process. Before developing a predictive model for the APS Upgrade, the system identification methodology is tested and validated against the present APS storage ring. This paper presents the system identification process, measurement results, and discusses model validation.
