  • Stator position feedback controller
    Patent number: 7268504
    Abstract: Stator position feedback controller. A first position monitoring device responds to the position of a stator supported for relative motion by a machine base. A second position monitoring device responds to the position of a carriage with respect to the machine base. An actuator is provided to move the carriage through interaction with the stator. A servo controller responds to the difference in the output of the first and second position monitoring devices to control the position of the carriage with respect to the machine base.
    Type: Grant

  • Precision motion control using feed forward of acceleration
    Publication number: 20040204777
    Abstract: High precision position control apparatus. An object supported on a frame of reference is moved by an actuator. A position sensor generates a position signal and an acceleration sensor affixed to the frame of reference generates an acceleration signal. A control system responds to the position signal and the acceleration signal to control the actuator to move the object to follow a commanded trajectory with reduced following error.
