The features of the mathematical description of the dynamics of models are considered, the problems of the theory of designing control systems for ekranoplane (or Wing-in-Ground effect vehicle or WIG-craft), taking into account aerodynamics and local loads and flexible dynamics. Flying at low altitude over an uneven surface is accompanied by powerful periodic and impulsive loads caused by unevenness of the underlying surface. In addition, with small changes in height, the controllability and stability of the ekranoplane significantly changes up to loss of stability. For the synthesis of the ekrano-plane control system, a new method for calculating the nonlinear mathematical model of the ekranoplane is proposed based on the CFD Comsol Multiphysics and Matlab programs. The simulation results are presented.
