| 摘 要： | 抖动控制是影响机械抖动激光陀螺性能的重要因素,基于激光陀螺的抖动动力学响应特性,研究了一种抖动控制回路解耦方法,指出相位反馈能实现机抖激光陀螺抖动谐振频率的稳定跟踪。稳定跟踪抖动谐振频率时,如果在抖动位置零点改变驱动信号幅度,则抖幅响应可以简化为一阶惯性系统响应,抖幅控制支路可以从抖动控制回路中解耦为一阶控制回路,实现抖动控制回路的解耦,提高了激光陀螺抖动系统的控制性能。

| Abstract: | Dither control is an important factor for the performance of dither ring laser gyro(DRLG).The decoupling method of DRLG dither control system is studied based on gyro oscillation characteristics.It is studied that the phase feedback is a good selection to trace resonant dither frequency. On tracing resonant frequency,as well as changing amplitude of dither drive signal on the zero-position-point,the dither amplitude responses can be simplified as a 1-order system,and the dither-amplitude-control is independ... |
