Research And Development Of Autoflight Control System Of Flight Simulator

Flight simulator is the most effective equipment for training pilot. Currently, the flight simulators that used in our country mostly imported from abroad. With the development of China's aviation industry,The developing of Domestic R & D flight simulator will play a positive role in China's aviation industry,the development of 6 degree-of-freedom Stewart Platform control technology and advanced computer technology as well as the extensive application,create fine conditions for it. In order to improve domestic flight simulator development and promote the development of civil aviation,we have established the "985—2" flight simulator key technology research platform construction projects , my project is the subsidiary-subject project-subject of the item,the main idea of the project is to research the flight simulator autoflight control system and related technology.Autoflight control system is regarded as a key system in aircraft and an important component for the flight simulator. It influences the flight simulator's indicators, for example fidelity and performance and so on. Autoflight control system is one of technologic indicators that can decide the grade of flight simulator. The topic discusses Autoflight Control System of large civil aircraft flight simulator. Firstly, the topic analyzes all functions and composition and theory of autoflight control system. Based on these analyses,the topic gives further analyzing of the logical relationship of the various functional modules and detailed designing of the logic of them. The designing purpose of the autoflight control system control policy design is to find a suitable flight control policy for large civil aircrafts simulator. Considering many special factors of large civil aircraft,such as safety and the higher demand of the control system for stability,the issue uses the classical control theory with relatively mature technology. The issue establishes corresponding control system software model by using of MATLAB/SIMULINK software. Through the designing of the control system architecture and adding links correction, autoflight control system has achieved satisfactory control effect. Based on the works mentioned above, the topic develops autoflight control system that is suitable for large civil aircraft flight simulator. The development in this topic lays the foundation to the development and improvement of flight control system of flight simulator. Meanwhile,the development process of the entire flight control system and technical problems during the research refers in this paper can also use for reference by developing of other similar systems.
