Abstract

UN SISTEMA DE CONTROL EN DONDE UNA UNIDAD DE CONTROL ELECTRONICO (14) GENERA UNA SEÑAL DE IMPULSION PARA QUE UN DISPOSITIVO HIDRAULICO (13L, 13R, 15) GIRE LA ESTRUCTURA (11) DE UN VAGON DE TREN (3) SOBRE UN EJE LONGITUDINAL (G) DEL VAGON PARA REDUCIR LA ACELERACION TRANSVERSAL NO COMPENSADA A LA QUE SON SOMETIDOS LOS PASAJEROS. EL SISTEMA DE CONTROL PRESENTA UN CIRCUITO DE DIFERENCIACION (37) Y UN CIRCUITO PROPORCIONAR (31), QUE ESTAN ABASTECIDOS CON UNA SEÑAL DE ERROR ({ZE}E) IGUAL A LA DIFERENCIA ENTRE UNA SEÑAL DE REFERENCIA ({ZE}C) Y UNA SEÑAL DE RETROALIMENTACION ({ZE}Z) QUE INDICA EL ANGULO REAL DE INCLINACION DE LA ESTRUCTURA. LAS SALIDAS DEL CIRCUITO DE DIFERENCIACION (37) Y EL CIRCUITO PROPORCIONAL (31) SON AÑADIDOS PARA GENERAR UNA SEÑAL DE IMPULSION PARA IMPULSAR EL DISPOSITIVO HIDRAULICO (13L, 13R, 15); Y EL CIRCUITO DE DIFERENCIACION (37) PRESENTA UNA GANANCIA DERIVADA (GD) QUE ES UNA FUNCION DE LA DERIVADA DE TIEMPO (D{ZE}E/DT) DEL MODULO DE SEÑAL DE ERROR ({ZE}E).A CONTROL SYSTEM WHERE AN ELECTRONIC CONTROL UNIT (14) GENERATES A DRIVE SIGNAL FOR A HYDRAULIC DEVICE (13L, 13R, 15) TO ROTATE THE STRUCTURE (11) OF A TRAIN WAGON (3) ON A LONGITUDINAL AXLE ( G) OF THE WAGON TO REDUCE THE UNCOMPENSED TRANSVERSE ACCELERATION TO WHICH THE PASSENGERS ARE SUBJECTED. THE CONTROL SYSTEM PRESENTS A DIFFERENTIATION CIRCUIT (37) AND A PROVIDE CIRCUIT (31), WHICH ARE SUPPLIED WITH AN ERROR SIGNAL ({ZE} E) EQUAL TO THE DIFFERENCE BETWEEN A REFERENCE SIGNAL ({ZE} C) AND A FEEDBACK FEEDBACK ({ZE} Z) INDICATING THE ACTUAL ANGLE OF INCLINATION OF THE STRUCTURE. THE OUTPUTS OF THE DIFFERENTIATION CIRCUIT (37) AND THE PROPORTIONAL CIRCUIT (31) ARE ADDED TO GENERATE A DRIVE SIGNAL TO DRIVE THE HYDRAULIC DEVICE (13L, 13R, 15); AND THE DIFFERENTIATION CIRCUIT (37) PRESENTS A DERIVED GAIN (GD) WHICH IS A FUNCTION OF THE TIME DERIVATIVE (D {ZE} E / DT) OF THE ERROR SIGNAL MODULE ({ZE} E).
