Abstract

在校正大气湍流畸变波前相差的自适应光学系统中，利用基于Levenberg-Marquardt学习算法的非线性反向传播神经网络技术（LMBP）对变形镜控制电压进行预测。以对受横向风影响的大气湍流畸变波前斜率数据为研究对象，通过数值仿真方法，研究了基于LMBP算法的自适应光学系统变形镜电压非线性预测控制算法。通过实验发现，预测电压和变形镜实际控制电压拟合效果良好。讨论了回溯帧数对预测效果的影响，并与基于递推最小二乘（RLS）算法的线性预测算法进行比较。对比结果表明，基于LMBP算法的非线性电压预测方法比基于递推最小二乘法的线性电压预测方法能更有效地降低系统由伺服延迟引起的误差。
