INDICATOR GYROSTABILIZER Russian patent published in 1998 - IPC

FIELD: gyroscopes, design of tracking systems. SUBSTANCE: indicator gyrostabilizer is composed of platform with single-axis suspension with which axis stabilizing motor is coupled kinematically. Platform carries two-degree-of-freedom gyro with transmitters of angle and moment along each axis of suspension. One transmitter of angle is connected via locking amplifier to transmitter of moment. Transmitter of angle put on axis parallel to axis of suspension of platform is connected to one of inputs of stabilization amplifier. Stabilization amplifier incorporates preamplifier, phase-sensitive rectifier, voltage and power amplifiers connected in series. Its output is connected to control winding of stabilizing motor. Increased stability and reliability of operation of gyroplatform are achieved thanks to insertion of adder into stabilization amplifier between phase-sensitive rectifier and power amplifier and of resistor into control winding of stabilizing motor. Resistor of positive feedback is connected via scaling amplifier to noninverting input of adder. Inverting input of adder is connected to output of phase-sensitive rectifier. Description gives relation to determine gain factor of scaling amplifier. EFFECT: increased stability and reliability of operation of gyroplatform. 1 dwg
