Title:
POSITION CONTROLLER
Document Type and Number:
Japanese Patent JPS5850009
Kind Code:
A
Abstract:
PURPOSE:To improve directional precision, by providing a circuit, which corrects deformation errors due to disturbance such as wind, in a position controller for an antenna. CONSTITUTION:An armature current if of a DC motor is detected by a current detector 7, and the detected signal is used not only as a current controlling feedback signal in a servo controlling circuit 2 cut also for improvement of directional precision in a deformation error operating circuit 13. The armature current of the DC motor is proportional to the torque generated by a motor, and the proportion of the wind torque out of motor generating torque is increased according as the antenna diameter is larger. Consequently, the motor armature current if is allowed to pass through an LPF, and the wind torque due to an average air speed is obtained approximately in the circuit 13 and is multiplied by a prescribed number of obtain a correction value. Thus, the directional precision of the antenna is improved.
