000612992 520__ $$aWithin the FLASH 2020+ upgrade project of the FLASH facility in Hamburg, the original FLASH beamline (FLASH1) will be completely remodeled and equipped with variable gap APPLE-III undulators, capable of controlling the polarization state of the FEL radiation. In the course of enhancing the operability of FLASH,  the influence of the variable undulator focusing in both  planes will be compensated by an automatic correction algorithm.The aim is to maintain a stable optics while minimizing optical changes.In this article, we discuss the basic stability concepts of a ``FUDU'' (focusing quadrupole, undulator, defocusing quadrupole, undulator) lattice, and compare several analytical approximations and numerical approaches.
