摘要

The problem of determining the aerodynamic parameters of the model of vehicle in the area of the ground-effect, intended for the synthesis of the control system, is considered. The determination of aerodynamic forces and moments for various stationary flight modes is successfully solved by experimental and numerical methods. Each control element is one more additional varied parameter. The volume of calculations is reduced if we consider only the movement in the neighborhood of the balancing modes. We calculate the centering and balancing of the vehicle for a given full model of the dynamics of the object, taking into account the limitations on the control parameters. The vector of control actions in a generalized form is limited to the maximum values of forces and moments. The tasks of centering, balancing and implementing hierarchical control are solved by mathematical programming methods. Synthesis of generalized control is carried out by classical or synergistic methods. Our preliminary calculation of aerodynamic parameters using the COMSOL Multiphysics software package and the CFD module allowed us to solve all these tasks and we will use it to further calculate the aerodynamics of stationary and non-stationary flight modes in the neighborhood of balancing values.
