(Iop Publishing LtdBristolInglaterra, 2011)
Projeto automático de controlador de velocidade sem sensor mecânico para motores de indução trifásicos
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2008-08-27)
This works proposes parameters estimation algorithm to auto-tune the control
laws of a speed sensorless servo. The identification process of the electrical and
mechanical parameters is based on recursive least squares ...
Planning and Projects of Secondary Electric Power Distribution Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2009-08-01)
