The control method of close-loop adaptive optical (AO) system with single wavefront sensor and multi-wavefront-correctors was proposed. The wave aberration was measured using single wavefront sensor. The wavefront aberrance was decomposed to lower rank wave aberrations and higher rank residual error by decoupling method and algorithm of limitative correction. In this way,different types of wave aberrations are corrected by different wavefront correctors respectively. The wavefront correctors with little elements are used to correct low spatial frequency wave aberration using Zernike wavefront modal algorithm. The wavefront corrector with more elements is used to correct the residual high spatial frequency wavefront error using direct gradient wavefront control algorithm. An adaptive optical system using a single Hartman wavefront sensor (HS) with 96 sub-apertures to control 19-element deformable mirror (DM),61-element deformable mirror and 127-element deformable mirror has been numerical simulated. It is proved that this method can improve the compensation ability of an adaptive optical system.
