A Novel method for online correction of amplitude and phase imbalances in sinusoidal encoders signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Resolvers and other sinusoidal transducers are angular position and speed sensors that produce supposedly perfect sine and cosine signals in which the angular position is encoded. Suitable converters are normally used to ...
