Method for active compensation control of any number of cylinders operated in parallel in order to achieve synchronous movements

摘要

A method for controlling any number of cylinders operated in parallel in order to achieve synchronous movements envisages that a desired value w be fed to each cylinder via a control circuit with a transfer function Gi and a feedback Hi. One of the control circuits is used as a master circuit. To control the cylinders relative to one another, the difference between the actual value of the master circuit and the actual value of the respective other control circuit is fed back and fed to the input of the respective other control circuit together with the desired value. <IMAGE>
