Features of designing control systems for WIG-craft

The method and software of joint design of a constructive scheme of a WIG-craft (ground-effect winged vehicle), details of its aerodynamic shape and control surfaces, a control system, taking into account the minimization of the load on pilots, are considered. The method and software of joint design of a constructive scheme of a ground-winged vehicle, a control system, taking into account the minimization of the load on pilots, are considered. It provides for the use of a single specialized application package, including Comsol Multiphysics and Matlab. Comsol Multiphysics provides imitation of conducting experiments in a wind tunnel for various ground-winged vehicle models and flight modes. The results of the experiments are stored in the form of data arrays and are used to calculate a nonlinear system of differential equations. The obtained equations are the basis for the study of the dynamic properties of an airplane, its stability and controllability in all flight modes in the zone of the screen effect. These equations are supplemented by dynamic models of gauges, steering gears, stochastic models of external disturbances, measurements of altitude, flight speed and orientation of an airplane. Upon receipt of unsatisfactory stability and controllability, it is proposed to change the aerodynamic form of an WIG and repeat the calculations. The calculation of the control system is carried out using Matlab.
