Patent GB-1186103-A (GB)
Title: Automatic Pilot System.
IPC: G05D1/02
Filed: 1967-04-13
Abstract: 1,186,103. Automatic steering control. TOKYO KEIKI SEIZOSHO K.K. April 13, 1967 [April 13, 1966], No.16985/67. Heading G3R. In an error-actuated control system for automatically maintaining a ship on a desired heading, the number of steering operations in a given time automatically controls the width of the dead band or the low-pass cut-off frequency of the control system to avoid too frequent operation of the steering in rough weather. In Fig.2, a D. C. signal representative of the course error of a ship is produced by a potentiometer 13 operated by the output of a differential gear 9 driven by a gyro repeater compass 12 and the ship's helm O. When this signal exceeds predetermined values, set in each sense by biased diodes D 1  D 2 , it is effective through an amplifier 5 to actuate a relay-operated rudder servomotor M which corrects the course. A potentiometer 15 operated by the servomotor applies a positional follow-up signal to the input of amplifier 5. A condenser 25 associated with diodes D 3  D 4  is capacitively coupled to the outputs of amplifier 5 and charges to a voltage dependent on the number of operations of the servomotor in a given time. This voltage, through an amplifier 27, determines the setting of relay-operated selector switches 21 associated with a potentiometer 18 to adjust the bias of diodes D 1  D 2 , and hence the dead band, so as to increase the latter and prevent too many operations of the servomotor, e.g. in rough weather. Sensitivity of control is manually adjustable by variable resistors 7. Details are given of suitable transistor relay circuits for controlling selector switches 21 and suitable biased transistor circuits which may replace the biased diodes D 1  D 2  . A digital type counter may replace condenser 25. In a modification, a low-pass filter replaces or supplements the dead band circuit so that only deviations of a sufficient duration are effective, and the time constant of this filter is automatically adjusted in dependence on the number of servomotor operations.
