Abstract

EN UN PROCEDIMIENTO PARA LA DETERMINACION DEL FLUJO MAGNETICO DE MAQUINAS ASINCRONAS, EN EL QUE MEDIANTE EL EMPLEO DE UN MODELO DE MAQUINA SE ESTIMA EL FLUJO DEL ROTOR A PARTIR DE MAGNITUDES MEDIDAS EN LA MAQUINA ASINCRONA, SE PRETENDE CONSEGUIR A BAJO COSTE UNA PRECISION NOTABLE INCREMENTADA. DEBERA SER AMPLIAMENTE INDEPENDIENTE DEL NUMERO DE REVOLUCIONES Y POCO SENSIBLE A LAS DESVIACIONES DE LOS PARAMETROS DEL MODELO RESPECTO A LOS VALORES VERDADEROS. ESTE PROBLEMA SE RESUELVE PRECISAMENTE PORQUE UTILIZA UN MODELO DE MAQUINA DE VARIOS ESCALONES, CON UN PRIMER MODELO (1) PARA EL ESTATOR Y UN SEGUNDO MODELO (2) PARA EL ROTOR, PORQUE EN AMBOS MODELOS LOS VALORES DE CALCULO DE LAS MAGNITUDES DEL ESTADO DEL FLUJO DEL ROTOR SON DETERMINADOS DE FORMA DIFERENTE Y PORQUE LA DIFERENCIA DE LOS VALORES DE CALCULO SON RETORNADOS AL PRIMER MODELO (1). EN UNA CONFIGURACION ESPECIAL SE DETERMINA, POR UN LADO EN EL PRIMER MODELO (1), EL VALOR ESTIMADO DEL FLUJO DEL ROTOR A MODO DE COMBINACION LINEAL DE LAS MAGNITUDES (USI1, ISI1) DE MEDICION DEL ESTATOR Y DE UNA MAGNITUD ESTIMADA DEL FLUJO DEL ESTATOR A LA SALIDA DE UN INTEGRADOR (7) DE FLUJO, Y POR OTRO LADO EN EL SEGUNDO MODELO (2), MEDIANTE UN VALOR ESTIMADO (I) DE LA CORRIENTE DEL ESTATOR CALCULADO SE DETERMINA UN VALOR ESTIMADO DEL FLUJO DEL ROTOR ACTUANTE A MODO DE SEUDOMAGNITUD DE MEDICION Y LA DIFERENCIA DE AMBOS VALORES RETROACTUA SOBRE LA ENTRADA DEL INTEGRADOR (7) DE FLUJO.
