    摘要: A motor driving device for driving a motor includes a motor driver, a speed control loop, a current control loop, and an arithmetic selecting module. The motor driver provides a current signal for the motor to output a speed signal. The speed control loop receiving the speed signal and a speed command, includes a first selector and two first arithmetic modules. The current control loop receiving the current signal, includes a second selector and two second arithmetic modules. The arithmetic selecting module outputs a first select command and a second select command to select an arithmetic module of the speed control loop and the current control loop correspondingly. The speed control loop provides a current command for the current control loop and the arithmetic selecting module. The current control loop provides a control signal for the motor driver to adjust the current signal thereby to adjust the speed signal.

    摘要: Servo controller for controlling a plurality of motors including a master motor and a slave motor cooperatively driving a movable member. The servo controller is configured to control the master motor and the slave motor based on position references for the master motor. The servo controller includes a master speed controller configured to calculate a reference torque for the master motor based on speed errors for the master motor. The slave speed controller is configured to calculate reference torques for the slave motor based on speed errors for the slave motor. Each of the reference torques includes a proportional torque part and an integral torque part. The servo controller is configured to calculate each of the integral torque parts based on the speed errors of the master motor and the speed errors of the slave motor, such that the torques due to the integral torque parts will be distributed equally between the master and slave motors or according to a predefined ratio.

    摘要: An automatic control system in the form of a servomechanism is disclosed which is especially adapted for position and velocity control for machine tools. The invention provides increased accuracy and enables high speed operation by utilizing input command signals with the controlled axis variable expressed as a function of a reference axis variable. A signal processor operates on the command signal to produce control signals for the servo, such as position, velocity and acceleration signals. Preferably the command signals take the form of first and second difference signals and the necessary time base signal is supplied from a signal generator connected with the reference axis drive means so as to produce a velocity signal corresponding to motion with respect to the reference axis. The system is implemented in a manner to accept digital input signals from an interpolator or computer and to produce analog control signals for the servo.

    摘要: Embodiments of the present invention are directed to compensating for force ripple of an apparatus driven by a force produced by a linear motor. In one embodiment, a method of compensating for force ripple comprises generating force commands for a trajectory starting at a plurality of starting positions of the apparatus driven by the linear motor to produce different trajectory motions based on the same trajectory at the plurality of starting positions, the force commands each including peaks of large acceleration/deceleration and valleys of low force levels; calculating an average of the force commands during large acceleration/deceleration generated based on trajectory motions for the plurality of starting positions; calculating a variation ratio of the force command for each trajectory motion to the calculated average of the force commands; and compensating for force ripple in the apparatus based on the calculated variation ratio to control the force applied by the linear motor to the apparatus.

    摘要: A method and an apparatus to control the rotation of an object. In the method, first and second actual control variables which vary as the object rotates are measured. It is determined whether the first actual control variable is smaller than a predetermined control variable. It is determined whether a period of time has elapsed if it is determined that the first actual control variable is smaller than the predetermined control variable. A difference between a physical quantity that is generated corresponding to the first actual control variable and the second actual control variable is obtained, and a control amount to control the object is determined by using the difference, if it is determined that the predetermined period of time has elapsed or the first actual control variable is larger than the predetermined control variable. Here, the predetermined control variable corresponds to a position to which the object should be rotated to stop the object at a desired position. The object stops precisely at the desired rotation position, thus enabling precise control of the amount of rotation of the object. The method and the apparatus may stop a roller precisely in a desired position when being used to control the rotation of the roller of an inkjet printer, thereby preventing the formation of black or white lines in a printed image.
