Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE AUTOCORRECCION DE AL MENOS UN PARAMETRO FISICO (X) DE UN SISTEMA DINAMICO, TAL COMO UN MOTOR DE COMBUSTION INTERNA EN EL QUE LA EVOLUCION EN EL TIEMPO DE DICHO PARAMETRO ES SIMULADA POR UNA FUNCION QUE TIENE EN CUENTA EL GRADIENTE (X) DE ESTE PARAMETRO, DE TAL MANERA QUE A CADA PASO DE CALCULO LA FUNCION DE SIMULACION CALCULA UN PARAMETRO SIMULADO (XS), CARACTERIZANDOSE DICHO PROCEDIMIENTO SEGUN LA INVENCION EN QUE CONSISTE EN: MEDIR UN ERROR ({EP}) ENTRE EL VALOR REAL (X) MEDIDO DEL PARAMETRO A UN PASO DE CALCULO DADO Y EL VALOR SIMULADO (XS) DE ESTE PARAMETRO EN ESTE MISMO CALCULO, - EN DEDUCIR UNA CORRECCION (+/-{EP}) A APLICAR AL CALCULO DEL GRADIENTE (X) DE ESTE PARAMETRO, CON EL FIN DE MODIFICAR SIMULTANEAMENTE, PARA EL SIGUIENTE CALCULO, LA FUNCION DE SIMULACION QUE PERMITE OBTENER EL VALOR SIMULADO (XS) DE ESTE PARAMETRO Y SU GRADIENTE (X). LA PRESENTE INVENCION SE APLICA EN EL CONTROL ELECTRONICO DE UN MOTOR DE COMBUSTION INTERNA.
