Abstract

DURANTE EL IMPULSO DEL MOTOR, SE MIDE EL COMPONENTE REAL DE LA CORRIENTE DEL ESTATOR REL (20) COMO UNA APROXIMACION A LA CORRIENTE DE TORSION (IT), Y SE OBTIENE UNA ACELERACION DE REFERENCIA COMO UNA APROXIMACION A LA ACELERACION DEL MOTOR, PARA SUMINISTRAR POR MEDIO DE UNA REGRESION LINEAL (22), LA INTERSECCION (Y) DE UNA LINEA QUE DEFINE LA RELACION ENTRE REL Y LA ACELERACION DE REFERENCIA AREF, DICHA INTERCEPTACION DEFINE LA REL A UNA VELOCIDAD ALTA Y CONSTANTE (REL ALTA VELOCIDAD CONSTANTE), PARA RELACIONAR LINEALMENTE (24) LA REL CONSTANTE CON UNA FRECUENCIA DE COMPENSACION FCOMP QUE SE SUMINISTRA A UN SUMADOR (4) PARA SUMAR FCOMP CON UNA FRECUENCIA DE REFERENCIA FREF USADA PARA INDICAR LA VELOCIDAD DE MOTOR (13). LA CORRIENTE I DEL ESTATOR Y LA AREF SE MUESTREAN DURANTE LA IMPULSION PORQUE EN ESE MOMENTO EL COMPONENTE REAL DE LA CORRIENTE DEL ESTATOR REL ES APROXIMADAMENTE IGUAL A IT.
