Abstract

SE DESCRIBE UN SISTEMA DE CONTROL DE UNA VALVULA DE ADMISION PARA EL MOTOR DE UN VEHICULO, QUE TIENE UNA VALVULA DE ADMISION CONTROLADA POR MEDIOS DE CONTROL ELECTRONICO. LOS MEDIOS DE CONTROL (21) SON OPERABLES PARA INCREMENTAR EL ESFUERZO SUMINISTRADO A LA VALVULA DE ADMISION (14) CUANDO ESTA SE APROXIMA A SU POSICION CERRADA, CON OBJETO DE REDUCIR EL EFECTO DE ADHERENCIA ESTATICA Y FRICCION EN RESPUESTA AL SISTEMA DE CONTROL. SE OBTIENE UN INCREMENTO EN EL ESFUERZO INCREMENTANDO MOMENTANEAMENTE LA GANANCIA DEL SISTEMA O SUMINISTRANDO UN PASO DE ENTRADA DE DETERMINADA MAGNITUD.A CONTROL SYSTEM OF AN ADMISSION VALVE FOR THE MOTOR OF A VEHICLE IS DESCRIBED, WHICH HAS AN INTAKE VALVE CONTROLLED BY ELECTRONIC CONTROL MEANS. THE CONTROL MEANS (21) ARE OPERABLE TO INCREASE THE EFFORT SUPPLIED TO THE INLET VALVE (14) WHEN IT IS APPROXIMATE ITS CLOSED POSITION, IN ORDER TO REDUCE THE EFFECT OF STATIC ADHESION AND FRICTION IN RESPONSE TO THE CONTROL SYSTEM. AN INCREASE IN EFFORT IS OBTAINED BY MOMENTALLY INCREASING THE GAIN OF THE SYSTEM OR BY PROVIDING AN INPUT STEP OF CERTAIN MAGNITUDE.
