  • Method and apparatus for positioning a movable element using a galvanometer actuator and pre-filtering
    Patent number: 6782296
    Abstract: The invention relates to a method and a device, whereby a galvanometer actuator (7) that is connected to the element and a control unit are provided. Said unit generates a control signal for the actuator for adjusting the element according to a desired position time history that can be freely predetermined, whereby the control unit detects the control signal by means of the desired position time history and by considering a model (4) consisting of the unit of the actuator and the element. Said model is a time discrete state space model and is selected in such a way that said model can predict the position time history of the element for a time history of the control signal and with predetermined exactness, whereby said time history of the control signal can be freely predetermined. The predetermined desired position time history is verified by the control unit and by means of a preliminary filter and is modified with regard to the feasibility thereof if required.
