ABSTRACT:
A servo-motor control system having a load that is supported by a gear ring. The gear ring and the associated load are rotated by a driving wheel that is connected to the shaft of a servo motor. At least one transmitter rotatably contacts the gear ring at a point substantially 90.degree. from the point of contact of the driving wheel. As the gear ring rotates, the transmitter generates a control signal that corresponds to the angle of rotation of the gear ring and includes a backlash signal component corresponding to either the magnitude or speed of the backlash and/or resilience of the servo system. A measuring means rotatably contacts the shaft of the servo motor and generates a servo operating signal corresponding to the operational angle of rotation of the servo motor. The control signal and the servo operating signal are combined by an adder to generate a difference output signal having a component corresponding to the negative backlash signal component. A position sensing gyro generates a signal corresponding to the movement of the load and the gyro signal includes a component corresponding to the backlash signal component. The gyro signal and the difference output signal are added to generate a feedback output signal from which the backlash signal component has been eliminated. The feedback signal is applied to control the operation of the servo motor.
