There’s a seemingly unending list of modifications or upgrades you can make to a 3D printer. Most revolve around the mechanical side of things, many are simple prints or small add-ons. This ...
Abstract: A nonlinear flux observer (NFO) sensorless flux weakening control method based on a fuzzy extended state observer phase-locked loop (ESOPLL) is proposed to enhance the sensorless control ...
Abstract: This article proposes to connect the minimum-order sensorless indirect field-oriented control to an independent flux estimator. The stability of the sensorless speed estimation and control ...
