Abstract

Un sistema de control controla una transmisión hidrostática que tiene una bomba de desplazamiento variable acoplada a un motor de desplazamiento fijo. La bomba tiene una placa oscilante que es controlada por una senal de control generada por el sistema de control. El sistema de control incluye un generador de senal de comando, un sensor de velocidad de motor detectada, un sensor de velocidad de motor para generar una senal de velocidad de motor, y una unidad de control que genera la senal de control en función de la misma. La unidad de control genera una senal de velocidad de motor deseada en función de la senal de comando de velocidad y la senal de velocidad del motor, genera una senal de corrección anticipante en función de la senal de velocidad de motor deseada, genera una senal de diferencia como una diferencia entre la senal de velocidad de motor deseada y la senal de velocidad de motor detectada, genera una senal integral aplicando una función integral a la senal de diferencia, generando una senal de suma como una sumatoria de la senal de comando de corrección anticipante y la senal integral, y generando la senal de control en funcion de la senal de suma.
