DSP Controls Hydraulic Axis

Advantages are shown by using the DSP for the real time online control of hydraulic axis. The interrupt latency time is the most important factor for equidistant position samples to control the velocity as accurately as possible. The trajectory calculations for the velocity and position are presented as well as their derivation for Scurvatures. The control of the velocity, as a function of the force, is the key factor for the exact cold molding processes. Other applications are discussed, for example, the use of Newton algorithm to determine the dead point of the hydraulic axis movement and the control of two different hydraulic paths.
