Title: Periodic function detection method for periodic oscillation technical system
Inventor: NEUBERT ROLF DR
IPC: G06F17/10
Filed: 1996-10-01
Granted: 1998-02-19
Abstract: The method involves using a computer to determine a periodic condition description (x (t) ) of a technical system which is subject to oscillations. A Hopf bifurcation point (HP) is determined for the system (101), and a bifurcation plane is determined, outgoing from the Hopf bifurcation point (102). The periodic condition description of the technical system emerges from a periodic solution for a point on a freely determined curve (K) which lies on a group of points on the bifurcation plane. The Hopf bifurcation point is pref. determined as a zero value of a real part of an energy distribution function in the technical system. The Eigenvalue is determined at that point, and the periodic condition description emerges from a periodic solution for the Eigenvalue.
