Harmonic Detection Based on the TLS Estimation Algorithm

Based on the Newton learning algorithm, a new algorithm for TLS estimation and its application in harmonic detection is presented in this paper. It is shown that the LMS algorithm and constrained anti-Hebbian algorithm are two examples of the proposed algorithm in this paper. To solve the contravention between the detecting precision and speediness, analog detecting architectures are studied. The simulation results show that its noise rejection capability is superior to those of the LMS and constrained anti-Hebbian algorithms and the new algorithm gives faster convergence and better precision than another two methods
