Abstract

OBSERVANDO LAS TABLAS 14,15 DE UN PRIMER CONTROL DE ENTRADA, TAL COMO LA TEMPORIZACION DE LA IGNICION, Y UN SEGUNDO CONTROL DE ENTRADA, TAL COMO LA DEMANDA DE COMBUSTIBLE, ESTAN DIRIGIDOS POR LAS VELOCIDADES DEL MOTOR 10A, 13 Y LA DEMANDA DE CARGA 10B PARA PROPORCIONAR LOS VALORES BASICOS. UN GENERADOR DE PERTURBACION 18 PERIODICAMENTE AVANZA Y RETARDA LA TEMPORIZACION DE LA IGNICION Y LA PENDIENTE DE LA VELOCIDAD DEL MOTOR RESPECTO A LA TEMPORIZACION DE LA IGNICION SE COMPARA 20 CON LA PENDIENTE DESEADA QUE OFRECE LA TABLA 16. EL ERROR DE PENDIENTE SE APLICA A LOS MECANISMOS 21,22,24 PARA CORREGIR LOS VALORES BASE DE LA TEMPORIZACION DE LA IGNICION Y LA DEMANDA DE COMBUSTIBLE DE ACUERDO CON UNA ESTRATEGIA DE CONTROL, DE FORMA QUE LA PENDIENTE DE LA VELOCIDAD DEL MOTOR SE CORRIGE AL VALOR DESEADO. DE ACUERDO CON UNA PRIMERA ESTRATEGIA DE CONTROL, SE HACE AUMENTAR UNA DE LAS ENTRADAS DE CONTROL (OC,OD) HASTA LA VARIACION MAXIMA Y ENTONCES, LA OTRA ENTRADA DE CONTROL SE MODIFICA (CE O DF) PARA CORREGIR LA PENDIENTE DE VELOCIDAD DEL MOTOR. DE ACUERDO CON UNA SEGUNDA ESTRATEGIA DE CONTROL, AMBAS ENTRADAS DE CONTROL SE VARIAN SIMULTANEAMENTE (OG O OH) CON UNA RELACION PREDETERMINADA ENTRE LAS VARIACIONES INDIVIDUALES DE ENTRADA DE CONTROL.
