基于时间功率谱反演生成的Kolmogorov湍流时间序列, 模拟分析了自适应光学控制系统跟踪回路与高阶误差校正回路在有限误差-3 dB带宽、 有时间延迟情况下的闭环校正残余误差, 得出了系统的跟踪残余方差、高阶残余方差与误差-3 dB带宽的数值拟合结果, 修正了系统有效带宽的表达式, 使其能更精确地估计校正残余方差.

Based on the time serial signal generated by power spectrum density inversion, the closed-loop compensation residual variances of tracking loop and high-order error correction loop with finite error rejection -3 dB bandwidth and time delay are simulated. The data fitting results of relationships between residual variances and corresponding error rejection -3 dB bandwidths are obtained. The system effective bandwidths are modified so as to make the estimate of residual variances more precise.-
