Circuit arrangement for controlling the speed of rotation of a hydrostatic machine

摘要

A control for the speed of rotation of a hydrostatic machine in which the controlled variable and generated in a speed controller and is made up of a proportional component and an integrating component is limited by a limiting signal which is also made up of a predetermined basic value and a ramp signal behaving proportionally to the actual pivot angle of the hydrostatic machine. The limiting signal thus limits the output signal of the speed controller so that a rapid response behaviour is obtained and fluctuations in the settling to the desired speed are reduced.
