TRIANGULAR DITHER DRIVE APPARATUS FOR A RING LASER GYROSCOPE

摘要

Control apparatus for an RLG dither motor (10) includes a digital phase shifter (40) for providing a clock signal related to the RLG position signal. A rate pulse generator (50) for receiving an amplitude word signal generated by a processor (28) at intervals determined by the clock signal provides a pulse rate signal related to the amplitude word signal. The pulse rate signal (51) is combined with the RLG position signal (33) to provide a second pulse rate signal which is integrated to provide a triangular dither drive signal.
