摘要

考虑了模型动力学数学描述的特点，提出了考虑空气动力学、局部载荷和柔性动力学的平面飞行器(或翼在地飞行器)控制系统设计的理论问题。低空飞行在不平坦的地面上，伴随着由下垫面的不平整引起的强大的周期性和脉冲载荷。此外，在高度变化很小的情况下，平面的可控性和稳定性会发生明显变化，甚至失去稳定性。针对平面控制系统的综合，提出了一种基于CFD Comsol Multiphysics和Matlab程序计算平面非线性数学模型的新方法。给出了仿真结果。

Mathematical Model and Control System of an Ekranoplan under the Action of Large Aerodynamic Loads

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.
