DOI: 10.1109/tie.2022.3213909
Abstract: Resolvers are universally employed as absolute angle sensors in motor control systems. Detecting the synchronous envelopes is an essential step during the resolver-to-digital conversion (RDC) process when calculating the angle. However, conventional filter-based envelope detection… read more here.

DOI: 10.1109/tim.2018.2882047
Abstract: To obtain a rotary motor’s position, resolver-to-digital conversion conventionally adopts phase-locked loop-based type-II angle tracking observer (ATO), which generally performs well yet incurs steady-state position error when the motor accelerates. It inevitably weakens the motor… read more here.
