An efficient algorithm for control over a phase-front corrector based on electrooptical crystals has been developed with the use of the method of piecewise linear approximation. The accuracy characteristics of the algorithm are analyzed for the cases assuming the presence of Poisson and Gaussian noise in control channels. The analytical equations are derived for the variance of error and for the correlation coefficients of results of phase front reconstruction, as well as the estimate of computational expenses.
