Frequency‐Domain Analysis of a Keldysh‐Like System
International Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 671-682, 25 January 2026.ABSTRACT Complex dynamics of the system, revealing flutter and first presented by M. Keldysh, is analyzed in the paper in the frequency domain, through the describing function method. Motivated by this analysis, a system with similar behavior, but suitable for the exact frequency‐domain analysis through the locus of a perturbed relay system (LPRS ...
