| 摘 要： | 采用传统的FIR低通滤波器对激光陀螺输出信号滤波后会产生较大的时间延迟,使得滤波后信号难以满足姿态控制系统的要求.为了保证响应时间与导航精度均满足需求,本文研究了低阶FIR低通滤波器与自适应IIR陷波器相结合的滤波方法.理论仿真和试验结果表明,该方法可以有效的消除激光陀螺抖动偏频信号,同时能够显著缩短时间延迟,具有工程实用价值.

| Abstract: | Filtered by the traditional low past FIR filter,the time delay of filtered GRL signal can not meet the requirement of flight attitude control system.A proper model of IIR notching filter is chosen firstly,then the method using both adaptive IIR notching filter and low order FIR filter is presented.By using this method,the dither bias can be effectively eliminated,at the same time the time delay is evidently reduced.The filtered GRL signal can meet the requirements of flight control system. |
