METHOD FOR DAMPING ROTOR NUTATION VIBRATIONS IN GYROSCOPE Russian patent published in 2016 - IPC G01C19/00 

FIELD: safety.

SUBSTANCE: invention relates to tracking systems (TS) with gyro drive as actuating mechanism (AM). For this purpose, angular velocity signal is measured of actuator body lengthwise axis oscillations, indicating its coordinates in coordinate system associated with body by means of angular velocity sensor of body (AVS_b) lengthwise axis vibrations, signals are generated, which indicate rotary system of rotor coordinates (RCS_r) based on signals of rotor rotation sensor relative to body (RRS_b) and housing rotation sensor (HRS), bearing angle sensor (BAS) signal is converted from RCS_r into fixed coordinate system of rotor (FCS_r), and signal AVS_b into fixed coordinate system housing FCS_b. Then converted BAS signal is differentiated, converted signal AVS_b subtracted from it, and obtained signal difference is converted to additional control signal, indicating coordinates of rotor angular velocity at outlet nutation link, at frequency of control signal for angular position of sight axis of homing head, and negative feedback is formed between output and input nutation link, subtracting it from control signal for angular position of sight axis of homing head.

EFFECT: technical result is provision of stable operation of TS.
