Embodiment Construction

[0024] The dynamic tuning gyro is an inertial device with dual input and dual output. In the force feedback state, it can measure the angular velocity along the two input axes. Due to the mechanical structure, there is coupling between the two measurement axes. The power-tuned gyro rotor has a fixed axis, and when the gyro shell rotates, the gyro main shaft will have a deflection angle relative to the shell. The annunciator of the gyroscope is used to detect the deflection angle of the main shaft and convert it into a voltage signal. The locked closed loop generates a control-regulated current signal that enters the torquer, and the torque generated by the torquer causes the gyro to precess to follow the movement of the housing.

[0025] The key to the design of the start-stop servo locking circuit of the moving base is to eliminate the coupling between the two axes, and to design a reasonable circuit to ensure that the rotor is always locked near the zero position during the ...

Description

technical field [0001] The invention belongs to the application field of a strapdown inertial navigation system power tuning gyroscope, and in particular relates to a start-stop servo locking circuit for a dynamic base of a power tuning gyroscope. Background technique [0002] Dynamically tuned gyroscopes (DTGs) are still widely used in various strapdown inertial navigation systems. The dynamically tuned gyro used in the SINS must work in a closed-loop locked state. Therefore, the servo lock loop is an important factor affecting the performance of the gyroscope. The traditional servo locking loop can only satisfy the locking of the rotor after the gyroscope reaches the tuning speed. When the gyroscope starts and stops under the condition of the moving base, the traditional servo locking circuit cannot lock the rotor near the zero deflection angle. When the moving base moves, the rotor will repeatedly hit the stoppers of the two axes, causing the flexible joints to frequent...
