本文致力于将一种力矩误差自动补偿方法应用于一种以自由进动的敏感元件组成的精密摆式陀螺罗盘和数字信息处理。研制出信息处理算法和陀螺罗盘误差理论。业已证实,主要的误差源是摆动频率的标定不精确性和敏感元件偏离子午面的有限转角所引起的误差;在扰动基座上,敏感元件在观测坐标内的强迫振动和系统的有害力矩影响着陀螺罗盘的精度,该有害力矩是由于进动频率的改变和误差引起的。实验证实了力矩误差自动补偿的有效性和误差的基本期望函数。“Zavod Arsenal”生产联合公司的中心设计室采用了研究结果,并用它来完善罗盘设计。
This dissertation is devoted to applying a method of automatic compensation of moment error to a precision gyro compass and digital information processing which is composed of sensitive elements that move freely. Developed information processing algorithms and gyroscopic compass error theory. It has been confirmed that the main source of error is the error caused by the calibration inaccuracy of the wobble frequency and the limited angular rotation of the sensitive element from the meridian. The forced vibration of the sensitive element in the observed coordinates and the harmful torque of the system are disturbed on the pedestal, The gyro compass accuracy, the harmful torque is due to precession frequency changes and errors caused. The experiment validates the validity of the automatic compensation of the torque error and the basic expectation function of the error. The Zavod Arsenal production joint company’s central design house uses the findings and uses it to refine the compass design.
