  • Controller structure for multiple mechanically coupled drive units
    Patent number: 9106169
    Abstract: A controller structure for more than two drive units coupled mechanically to a movable element includes a position measuring device for determining an actual position of the movable element and a position controller for calculating a setpoint speed from a setpoint position and the actual position, the position measuring device and the position controller jointly serving all drive units. Each drive unit, however, has a speed controller of its own. The drive units are configured either as master or as slave, individual drive units also being able to assume both functions. A torque-master-slave controller ensures a compensation of the torques between the drive units.
