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.THE PRESENT INVENTION REFERS TO A SELF-CORRECTION PROCEDURE OF AT LEAST ONE PHYSICAL PARAMETER (X) OF A DYNAMIC SYSTEM, SUCH AS AN INTERNAL COMBUSTION ENGINE IN WHICH THE EVOLUTION IN THE TIME OF SUCH PARAMETER IS SIMULATED BY A FUNCTION THAT HAS IN THE GRADIENT (X) OF THIS PARAMETER COUNTS, IN SUCH A WAY THAT THE SIMULATION FUNCTION IS CALCULATED BY EACH STEP OF CALCULATION A SIMULATED PARAMETER (XS), CHARACTERIZING SUCH A PROCEDURE ACCORDING TO THE INVENTION WHICH CONSISTS OF: MEASURING AN ERROR ({EP}) BETWEEN THE REAL VALUE (X) MEASURED FROM THE PARAMETER TO A CALCULATION STEP GIVEN AND THE SIMULATED VALUE (XS) OF THIS PARAMETER IN THIS SAME CALCULATION, - IN DEDUCTING A CORRECTION (+/- {EP}) TO APPLY TO THE CALCULATION OF THE GRADIENT (X) OF THIS PARAMETER, IN ORDER TO MODIFY SIMULTANEOUSLY, FOR THE FOLLOWING CALCULATION, THE SIMULATION FUNCTION THAT ALLOWS TO OBTAIN THE SIMULATED VALUE (XS) OF THIS PARAMETER AND ITS GRADIENT (X). THE PRESENT INVENTION APPLIES TO THE ELECTRONIC CONTROL OF AN INTERNAL COMBUSTION ENGINE.
