RESONANT WINGBEAT TUNING CIRCUIT USING STRAIN-RATE FEEDBACK FOR ORNITHOPTIC MICRO AERIAL VEHICLES

摘要

A resonant wingbeat tuning circuit automatically tunes the frequency of an actuating input to the resonant frequency of a flexible wing structure. Through the use of feedback control, the circuit produces the maximum flapping amplitude of a mechanical omithoptic system, tracking the resonant frequency of the vibratory flapping apparatus as it varies in response to changes in flight condition, ambient pressure, or incurred wing damage.
