| Abstract: | 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. |
