Abstract
"MéTODO DE ESTIMATIVA". A invenção refere-se a um estimador de corrente de campo para estimar a corrente de campo em um aparelho síncrono excitado sem escovas que compreende um excitador que tem uma parte de estator e uma parte de rotor que compreende um retificador, e uma máquina que tem uma parte de estator e uma parte de rotor e um enrolamento de campo. O estimador de corrente de campo compreende: uma primeira unidade de cálculo, que calcula as voltagens (V~ ra~, V~ rb~, V~ rc~) da parte de rotor do excitador com base nos valores medidos da corrente (i~ s~) e da voltagem (u~ s~) da parte de estator do excitador, por meio de um modelo matemático do excitador, uma segunda unidade de cálculo, que calcula a voltagem (v~ ff~) do enrolamento de campo com base na voltagem calculada (V~ ra~, V~ rb~, V~ rc~) da parte de rotor do excitador, por meio de um modelo matemático do retificador, e uma terceira unidade de cálculo, que calcula a corrente de campo (i~ ff~) do enrolamento de campo com base na voltagem calculada (v~ ff~) do enrolamento de campo, por meio de um modelo matemático do enrolamento de campo.
