3D Simulation Of Fixed Wing Aircraft Flight Based On Multi-dimensional Taylor Network Optimal Control

Aircraft is one of the most important inventions of mankind,and its wide application in various fields has profoundly changed the way of life and the style of war.The aircraft control system is an important part of the aircraft system,which has a significant impact on the performance of the aircraft,and is also an important guarantee for the safe flight of aircraft and the completion of a variety of complex applications.With the development of technology,computer simulation and virtual reality are applied to the design and development of aircraft.3D simulation can make use of computer graphics technology to truly reproduce the flight process of the aircraft,providing an intuitive and convenient interface for the simulation data.In this thesis,the controller design and 3D simulation technology of fixed wing aircraft are studied.The contents include the following parts:1.Based on the analysis of the aerodynamic configuration and force of the fixed wing aircraft,the mathematical model of the whole channel is derived,accompanied with the analysis of the characteristics of the model.2.In this thesis,a flight control method for fixed wing aircraft based on the multi-dimensional Taylor network(MTN)optimal control is proposed.According to the characteristics of the model,the longitudinal and lateral attitude controller is designed.The method of parameter adjustment is also studied,and the parameters of the controller are adapted by the simplex method.Then the flight control system is simulated on the MATLAB platform.Finally,a comparison experiment is given to illustrate the advantages of MTN compared to PID and sliding mode variable structure control in response speed and anti-jamming performance..3.The tools and knowledge needed for 3D animation simulation are introduced,where the OpenGL rendering pipeline and geometric transformation are explained.4.The construction method of the key elements in rendering scene is studied,which mainly includes the introduction of the third party model,the algorithm of terrain generation and the realization of the sky.5.According to the above,the three-dimensional simulation program of the aircraft flight is developed with MFC,and the real time communication with the MATLAB simulation program is also realized,so that the simulation data can be presented to the user in the form of animation.6.What have done is concluded,at the same time the outlook for further follow-up work is offered.
