A novel method for estimating the angle from analog co-sinusoidal quadrature signals
(
Elsevier
, 2008 , Article)
The paper presents a new low cost and accurate method for determining the angle from sine and cosine signals produced by resolvers and sinusoidal encoders. In the proposed scheme, multiple phase-shifted sinusoids (PSS) are ...
