摘要
将带有遗忘因子的自适应滤波技术应用于光纤陀螺的输出数据的滤波中,提高了滤波器对环境的适应能力,增强了滤波器的鲁棒性,克服了由于噪声变化引起的滤波发散现象。仿真结果证明:自适应滤波技术较卡尔曼滤波能更为有效地减小陀螺的随机误差。
We employ the adaptive filter with forget—coefficient to reduce the random errors of fiber optic gyro's output. And the adaptive filter has robustness and overcome the filter divergence caused by uncertain noises.The simulation re- sults prove that the adaptive filter is more effective in reducing the FOG's random errors than common Kalman filter.
