Digital servo control system based on gyrocompass and processing method

Abstract

The invention provides a digital servo control system based on a gyrocompass. A main control processing module is used for acquiring the signals of an 8-shaped coil detection module, an electromagnetic pendulum detection module and an accelerometer detection module, processing the signals, starting a gyroscope, generating a pitching motor operation control instruction and an azimuth motor operation control instruction, and tracking and controlling the operation of a pitching motor and an azimuth motor in real time. According to the system, software debugging can be conducted with the main control processing module directly, the debugging method is simple, flexible design can be realized, and the problem that the stability of an existing servo control system is poor due to the fact that the characteristics of devices are affected by environment temperature is solved. According to a processing method of the digital servo control system based on the gyrocompass, the acquired signals output by an 8-shaped coil, an electromagnetic pendulum and an accelerometer can be processed, and the gyrocompass is controlled to stay in the meridian plane and points north stably.

Description

technical field [0001] The invention relates to the field of ship navigation, in particular to a digital servo control system and a processing method based on a gyro compass. Background technique [0002] The gyro compass, also known as the gyro compass, is a kind of true north reference made by using the two basic characteristics of the gyroscope's fixed axis and precession, combined with the earth's rotation vector and gravity vector, and with the help of control equipment and damping equipment. Pointing instruments, precision navigation aids that can help a ship determine its heading or target azimuth. Compared with the traditional magnetic compass, it has the characteristics of high precision, stable heading and no influence of magnetic field. The gyro compass is equipped with gyro balls, pitch motors, azimuth motors, electromagnetic pendulums, accelerometers, magnetic sensors, temperature sensors, etc. Among them, the gyro ball is the key component of the operation of...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing servo control systems are implemented by adjusting the components on the hardware circuit during system debugging, such as adjusting the resistance and capacitance values ​​in the resistance-capacitance network. The system debugging is troublesome, and because most components The characteristics will be affected by the ambient temperature, which leads to the stability of the servo control system is easily affected by the change of the ambient temperature, resulting in drift, the servo control system is difficult to achieve flexible design
