Abstract

EL REGIMEN DE MARCHA EN VACIO (RPM) DE UN MOTOR DE COMBUSTION INTERNA (E) SE REGULA UTILIZANDO UNA UNIDAD DE CONTROL ELECTRONICA (ECU) COLOCADA PARA GENERAR UNA SEÑAL (ADV) PARA CORREGIR EL AVANCE DEL ENCENDIDO Y UNA SEÑAL (VAE) PARA VARIAR EL PILOTAJE DE UNA VALVULA DE SOLENOIDE (F) COLOCADA EN UN CONDUCTO (D) QUE PONE EN DERIVACION UNA VALVULA DE MARIPOSA (B) QUE CONTROLA EL SUMINISTRO DE AIRE AL MOTOR (E). CON ESTE FIN, LA UNIDAD ELECTRONICA (ECU) ADQUIERE LA VELOCIDAD INSTANTANEA DEL MOTOR (E) Y DE LA PRESION DE AIRE (MAP) EN EL COLECTOR DE ADMISION (A) MEDIANTE EL USO DE SENSORES (1, 2). LA UNIDAD ELECTRONICA (ECU) IMPLEMENTA UN TIPO DE CONTROL LQI (LINEAL -CUADRATICO-INTEGRAL) BASADO EN UN MODELO MATEMATICO LINEAL DEL MOTOR (E) .
