Paper Abstract

Resonance tracking control of harmonic oscillators whose natural frequency is unknown is investigated from a Lyapunov stability perspective. In particular, a periodically-modulated cosine driver (PMCD) is investigated for this purpose. The proposed resonance tuner is time-synchronized with periodic sampling of the harmonic oscillator's output to ensure that an analytical relationship exists between the drive frequency and the tracking error. This relation defines a class of discrete time nonlinear systems whose origin, is shown to be asymptotically stable.
