Hopf resonators
Web15 mei 2011 · Hopf bifurcation 1. Introduction; experiments and observations For various designs of extensional MEMS resonators, fabricated in SOI (Silicon-on-Insulator, thin Si-wafers), certain driving conditions are observed to cause the response to show saturation, without any evidence of physical obstruction. WebThe system has a Hopf bifurcation at µ = 0. We have ω = −1, d = 1 2 and a = −1 8, so the bifurcation is supercritical and there is a stable isolated periodic orbit (limit cycle) if µ > 0 …
