Abstract
In this study, the direct wavefront gradient algorithm is used to calculate the control voltage of the deflection mirror. Considering the control voltage as the input of the fuzzy controller, the fuzzy rule base is established and the three parameters of the proportional-integral-derivative controller are obtained using dual fuzzy control. In addition, a weight factor and threshold judgment are included to correct the control voltage and realize parameter self-tuning. A simulation and experiments demonstrate that this method can effectively correct the wavefront distortion signal and improve the system response speed. Moreover, it can reduce the difficulty of parameter adjustment and meet the requirements of laser communication for wavefront correction.
