CONTROLLER STRUCTURE FOR MULTIPLE MECHANICALLY COUPLED DRIVE UNITS

摘要

The invention relates to a controller structure for more than two drive units (10) which are mechanically coupled to a movable element (1). The controller structure has a position measurement device (4) for determining an actual position (Xact) of the movable element and a position controller (5) for calculating a target speed (Vnom) from a target position (Xnom) and the actual position, wherein the position measurement device and the position controller serve all drive units together. Every drive unit each has a dedicated speed controller (6). The drive units are configured either as masters or slaves, wherein individual drive units can also assume both functions. A torque master-slave controller (8) provides for equalization of torque between the drive units.
