发明名称 HYDRAULIC CYLINDER CONTROL
摘要 A system and methods for controlling operation of hydraulic cylinders includes monitoring position of the cylinders relative to one another, and correction of misalignment of the cylinders should they become misaligned. Further, monitoring can be of a swing-type door operated using the cylinders, which can operate the door at different speeds. Further, as the door creeps open from a closed position or closed from an open position, correction is also made.
