Abstract
The resonator-based observer has been developed for measuring the harmonic components of a periodic signal with known fundamental frequency. In certain applications, the signal to be processed is sparse in the frequency domain: a subset of its harmonic components have negligible amplitude. This paper presents some extensions of the resonator-based observer which can exploit this sparsity to speed up the convergence. The performance of the proposed structures is demonstrated by simulation examples.
