摘要
介绍和分析了一种利用校正残差进行实时迭代的自适应控制算法,可以应用到校正大气湍流的实际自适应光学系统。利用61单元自适应光学系统上实际采集的大气湍流扰动信号,实现了自适应控制算法,并对这种算法的收敛性、稳定性、控制效果等进行了计算机仿真研究,与常规PID算法进行了比较。
An adaptive control algorithm that its real-time iteration is carried out by means of residual error correction is introduced and analyzed. It can be applied to a practical adaptive optical system for correcting atmospheric turbulence. The adaptive control algorithm can be implemented by using the disturbance signal of atmospheric turbulence practically sampled with 61-element adaptive optical system. The convergence, stability and control effect of this algorithm are simulated with a computer. A comparison with common PID algorithm is carried out.
