Steady state analysis of free or forced oscillators by harmonic balance and stability investigation of periodic and quasiperiodic regimes
Résumé
This article presents a practical and effective method to analyze the steady state regimes, periodic or quasi-periodic, and the stability of free and forced oscillators, based on the use of voltage and current probes. The efficiency of this method comes from the fact that it converts the analysis of an autonomous circuit into the analysis of a series of closely related nonautonomous circuits, which in turn relies on the power of the harmonic balance equation for these kinds of systems. The effectiveness of the method is shown by full analysis of a practical example.
