DOI: 10.1109/tii.2022.3162302
Abstract: In this article, we studied the parameters identification problem for the single sinusoidal signal based on the finite-time observer technique. After representing the sinusoidal signal with known frequency as a second-order time-invariant system, a finite-time… read more here.
