Abstract
The present invention provides a method for pressure control of an adjustable pump for a hydraulic system including at least a load. Depending on the size of the system, i.e. the servo cylinder, hydrostatic machine and the line tubing, the fluid volume contained in the system between the adjustable pump and the low pressure side of the load is largely different. In controlling the load pressure in such a system, for example a press or a molding machine for plastic material, a pressure controller adaptively and automatically adjusts the damping factor of the controller and thus the controlling quality independent of the fluid volume of the system to a constant value. It is a benefit of the invention that all adjusting operations of the pressure controller are eliminated which have been necessary heretofore to obtain an appropriate control of the fluid system.
