Methods and systems for correcting position errors for a multi-leaf collimator (MLC) are provided. A method may include determining a first position for each of the plurality of leaves. The information associated with the first position may include a first movement direction and a first angle. A movement of the each of the plurality of leaves along the first movement direction may be configured to move toward or away from a center of the radiation field. The method may also include determining an offset value associated with the first position based on the first angle and the first movement direction; and determining a target position of the each of the plurality of leaves based on the offset value.

A method for correcting a position error for a motion terminal driven by a driving component may include obtaining a first displacement of the motion terminal acquired by a first sensor associated with the driving component. The method may also include obtaining a second displacement of the motion terminal acquired by a second sensor associated with the motion terminal. The method may further include determining an offset value based on a difference between the first displacement and the second displacement. The method may include determining a calibration displacement value relating to the first displacement based on the offset value.

A rotary electromagnetic actuator for car lamp low beam and high beam light switching device, comprises a shell (), a rotor (), a stator (), a rotating shaft () and an end cover (). The stator is fixedly installed in the shell to form a pair of arc-shaped stator magnetic poles () on which electric excitation can be applied; the rotor, as an arc-shaped permanent magnet, is fixed on the rotating shaft and is located in a magnetic field space of the arc-shaped magnetic poles of the stator; and the rotor is matched with the arc-shaped stator magnetic poles to form a closed magnetic circuit with an air gap (); two swing bars () are connected to two ends of the rotating shaft respectively.
