  • Abstract
    A hybrid observer to estimate the frequencies of a saturated multi-frequency signal is proposed. The observer is based on the Immersion and Invariance technique combined with a high-gain approach. This paper is a (semi-global) generalization of the result in [1] to the case of multiple frequencies.
