Abstract

Las técnicas para medir la presión en el cilindro incluyen recibir una señal analógica de presión de cilindro indicativa de la presión en un cilindro de un motor y una señal de posición angular indicativa de una posición angular del motor. La señal analógica de presión de cilindro se convierte a una señal digital de presión de cilindro al (i) enventanar la señal analógica de presión de cilindro en el dominio angular utilizando la señal de posición angular y al (ii) muestrear la señal analógica de presión de cilindro enventanada en el dominio temporal, y la señal digital de presión de cilindro se filtra en el dominio temporal para obtener una señal digital de presión de cilindro filtrada. Una presión medida en el dominio angular se obtiene al muestrear la señal digital de presión de cilindro filtrada utilizando la señal de posición angular, y la operación del motor se controla utilizando la presión de cilindro medida.
