A novel filtering algorithm for the resolver position signal based on recursive least squares and phase‐locked loop

Abstract This paper presents a novel filtering algorithm for the resolver position signal based on recursive least squares (RLS) and phase‐locked loop (PLL). The proposed RLS‐PLL‐based algorithm designs a harmonic iterative estimation and elimination mechanism, which can accurately estimate and elim...
