The invention discloses a stable platform stabilizing method based on a fiber-optic gyroscope. The method comprises a step of establishing a platform stabilizing system based on a fiber-optic gyroscope, wherein the system comprises a carrying vehicle (8), a stabilizing platform (6), an upper computer (1), a gyroscope signal acquisition circuit (3), an AD (analog / digital) conversion circuit (2), a servo driver (4), an AC (alternating current) permanent magnet synchronous motor (5) and a fiber-optic gyroscope (7). The gyroscope signal acquisition circuit (3) acquires a fiber-optic gyroscope signal and sends the fiber-optic gyroscope signal to the upper computer (1); the AD conversion circuit (2) outputs a stabilizing control signal to the servo driver (4); the servo driver (4) drives the AC permanent magnet synchronous motor (5) to rotate; the AC permanent magnet synchronous motor (5) drives the stabilizing platform (6) to move; and therefore, the stabilization of the stable platform based on a fiber-optic gyroscope is realized. The stabilization precision of the method can reach 5mrad, and the stabilization time of the platform can reach 48 hours.
Description
technical field [0001] The invention relates to a method for stabilizing a stable platform, in particular to a method for stabilizing a stable platform based on an optical fiber gyroscope. Background technique [0002] The stable platform can keep the equipment on the vehicle under stable control when the carrier of the missile weapon system is moving, and can compensate for changes in the attitude of the equipment caused by the carrier's swaying and turbulent movement, ensuring that its attitude is not affected by the movement of the carrier. According to the different stabilizing measuring devices, the current stabilizing methods include inclination sensor stabilizing method, liquid floating gyro stabilizing method and fiber optic gyro stabilizing method. The method of using the inclination sensor as a stabilizing element is to install the inclination sensor on the carrier, and the upper computer controls the stable platform by collecting the angle of the inclination senso...
