Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA PRODUCIR LA REFERENCIA DE VELOCIDAD PARA EL MOTOR DE UNA GRUA CUANDO EL CONVERTIDOR (4) QUE ALIMENTA EL MOTOR (2) ESTA CONTROLADO POR MEDIO DE AL MENOS UN CONTROLADOR (8) QUE, PARA PERMITIR QUE LA REFERENCIA DE VELOCIDAD SE CAMBIE, TIENE UNA POSICION DE CONTROL EN LA QUE LA REFERENCIA DE VELOCIDAD SE CAMBIA SEGUN UNA FUNCION DE TIEMPO. DE ACUERDO CON LA INVENCION, AL MENOS DURANTE LA ACELERACION LA DERIVADA DE TIEMPO (A SUB 1, A SUB 2) DE LA REFERENCIA DE VELOCIDAD DEL MOTOR SE CAMBIA DURANTE LA ETAPA DE CONTROL QUE SIGUE A LA ACELERACION INICIAL.
