The effect of time-delayed feedback controller on an electrically actuated resonator

摘要: This paper presents a study of the effect time-delayed feedback controller on dynamics Microelectromechanical systems (MEMS) capacitor actuated as resonator by DC and AC voltage loads. A linearization analysis is conducted to determine stability chart linearized system equations function time delay period gain. Then method multiple-scales applied response for small vibration amplitude It shown that negative time-delay control gain can lead unstable responses, even if relatively compared voltage. On other hand, positive considerably strengthen in fractal domains. We also show how be used damping MEMS, increasing or decreasing, tuning period. Agreements among results shooting technique, long-time integration, basin attraction with perturbation are achieved.
