It is considered the problem of the increase of the efficiency of adaptive control in the conditions of strong turbulence by flexible corrector with the sufficiently large number of freedom degrees. The methods of the construction of the more complex numerical models of the flexible mirrors are based on the solution of the equation of mirror deformations. It is showed that the increase of actuators number on mirror model not influences on the correction efficiency. The cause of low quality of the control in the conditions of strong turbulence consists in the presence of large number of dislocations on the surface of wave front. It was given the numerical experiment at the propagation of the laser radiation in the conditions of strong turbulence. The control was realized by the using of prior annihilation of the dislocations with opposite sign dislocations which are defined in same area of the wave front.
