    摘要: A control system for controlling a position or position related quantity of an object is provided. A measurement system is configured to measure a position or position related quantity of the object. A controller is configured to provide a control signal on the basis of the measured position or position related quantity. A actuator actuates the object on the basis of the control signal. A filter unit, which may be a partial order filter unit, filters the measured position or position related quantity.

    摘要: A method for damping an object in two or more degrees of freedom, including measuring a position quantity at each of the two or more measurement locations; extracting from the measured position quantities a measurement signal for each dynamic mode; feeding the measurement signal of a dynamic mode to a controller unit associated with the respective dynamic mode, the controller unit providing for each dynamic mode an output signal on the basis of the respective measurement signal; and providing a control signal to each of the two or more actuators, the control signal for each actuator being based on output signals of one or more controller units.

    摘要: An encoder-type measurement system is configured to measure a position dependent signal of a movable object, the measurement system including at least one sensor mountable on the movable object a sensor target object mountable on a substantially stationary frame, and a mounting device configured to mount the sensor target object on the substantially stationary frame. The measurement system further includes a compensation device configured to compensate movements and/or deformations of the sensor target object with respect to the substantially stationary frame. The compensation device may include a passive or an active damping device and/or a feedback position control system. In an alternative embodiment, the compensation device includes a gripping device which fixes the position of the sensor target object during a high accuracy movement of the movable object.
