Abstract
SE DESCRIBE UN SISTEMA DE CONTROL DE LA VELOCIDAD DEL FLUJO PARA MEDIR EL CAUDAL DE TINTA QUE PASA A TRAVES DE UN SISTEMA DE CHORRO DE TINTA. EL SISTEMA DE CONTROL DEL CAUDAL RECIBE UNA SEÑAL DE ERROR INDICATIVA DE LA DESVIACION DEL CAUDAL DE UN VALOR ESTABLECIDO. EL SISTEMA INCLUYE UN CONTROL PROPORCIONAL (P), INTEGRAL (I) Y DERIVATIVO (D) PARA GENERAR UNA SEÑAL DE CONTROL BASADA EN LA MAGNITUD Y EN EL SIGNO DE LA SEÑAL DE ERROR. LA SEÑAL DE CONTROL ES UTILIZADA PARA CONTROLAR EL TIEMPO DE ENCENDIDO DE UNA VALVULA DE RELLENO QUE AÑADE TINTA DE RELLENO AL SISTEMA A MEDIDA QUE ESTA SE PRECISA PARA MANTENER UN FUNCIONAMIENTO SATISFACTORIO. EN UN DISEÑO PREFERIDO, EL CONTROLADOR PROPORCIONAL, INTEGRAL Y DERIVATIVO TIENE UN DISPOSITIVO DE REDUCCION DEL RUIDO QUE UTILIZA CIRCUITOS LIMITADORES Y FILTROS DE PASO BAJO. ADEMAS, PUEDE UTILIZARSE UNA SUMA CONDICIONAL PARA MINIMIZAR LAS "OSCILACIONES" EN NIVELES BAJOS DE SEÑAL DE ERROR.
