Abstract

EN UN METODO PARA CALIBRAR AUTOMATICAMENTE UN CONTROLADOR PARA UN SISTEMA CONTROLADO DE GOBIERNO DE VALVULA, EL CONTROLADOR ESTA COLOCADO EN MODO DE AJUSTE, ENTONCES LOS ESTADOS DE LA VALVULA SE MODIFICAN DENTRO DE UN MARGEN DE OPERACION. EN NIVELES PREDETERMINADOS DE OPERACION, LOS ESTADOS DE LA VALVULA SE MANTIENEN EN VALORES PREESTABLECIDOS MIENTRAS EL SISTEMA REALIZA SU MEDIDA. DESPUES DE QUE TODO EL MARGEN DE OPERACION DE LA VALVULA HAYA SIDO CUBIERTO, LOS AJUSTES SE HACEN PARA CAMBIAR LAS CURVAS CARACTERISTICAS DE LA VALVULA CORRESPONDIENDO A MODOS DIFERENTES TALES COMO MODO DE VALVULA SIMPLE Y VALVULA SECUNENCIAL. OTROS PARAMETROS DE CONTROL PUEDEN SER AJUSTADOS POR EVALUACION DE LAS FUNCIONES DEL SISTEMA DURANTE LA OPERACION NORMAL.FIG 5.
