Abstract

Se provee un sistema de control para un sistema de accionamiento/direccion para un vehículo de orugas que tiene una bomba de direccion hidráulica impulsadapor un motor que acciona un motor de direccion hidráulico. La bomba de direccion responde a sen ales de control de la bomba de direccion, y un volante operadopor un conductor genera las senales de comando de direccion. Un motor de direccion provee una entrada a un mecanismo diferencial accionador de orugas queresponde al menejo del volante y ac ciona las orugas de izquierda y derecha, haciendo girar al vehículo. El sistema de control incluye un sensor de posicion delvolante, un sensor de posicion del motor de direccion y un sensor de velocidad de rueda. El sistema de control genera un valor de desplazamiento del motor enfuncion de la posicion del volante y la velocidad de rueda. El sistema de control también también genera un valor de error de posicion de motor en funcion delvalor de posicion deseado y de las senales de posicion real d el motor de direccion y genera las senales de control de la bomba de direccion en funcion de lassenales de error de posicion del motor de direccion.
