The Optimization Of 6-dof Flight Simulator Washout Filter Subsea Control Method Base On The Fuzzy Control Theory

Electric six degrees of freedom of flight simulators, is used to simulate the aircraft in flight equipment. Flight Simulator has become the best way to achieve better and more economical research flight and flight training purposes or even the only way. 6-DOF flight simulator used in large aircraft engineering design and simulation can save hundreds of millions of flight costs. Using flight simulators instead of real aircraft flight training equipment, you can save a lot of aviation fuel, the combustion exhaust and reducing carbon dioxide emissions, with environmental benefits. At present, China’s civil aviation industry throughout the existing flight simulators are imported from abroad, manufacturing simulator must provide aircraft parameters, flight data, performance parameters, dynamic performance and other information, which is foreign to fully grasp the techniques of civil aircraft condition, both a lot of money expended, and discharge the technical secrets. It has a high value on research electric six degrees of freedom of flight simulators, and has a very important impact on the future development of China’s large aircraft.As a Flight Simulator vector parallel six degree of freedom motion system is a flight simulator very important part, which provides aircraft movement during the pilot can feel momentary overload dynamic, sustained sense of gravity and some jitter components impact information so flight simulation is more close to the real flight. Its essence is controlled by a digital computer in real time and can provide pitch roll; yaw, lift, longitudinal and lateral translation of the translation transient overload six degrees of freedom simulation equipment. Therefore, the motion system performance will be directly related to the fidelity flight simulation. The Parallel six degrees of freedom motion system of organization theory, key components and control strategies is to exercise systematic structural optimization, enhance sports performance Flight Simulator key technology, research and optimization of the control system will directly determine the similarity realistic simulation of actual flight.For the issues raised above, this article will depart classical control methods, based on fuzzy control theory 6-DOF flight simulator wash out optimization filter control method, making the simulator gives pilots flying actual aircraft flight dynamic and dynamic more close to the original basis, so as to achieve a better experience effects and training. This paper will analyze a variety of methods, experiments on the washout algorithm to optimize the final design SIMULINK block diagram using MATLAB software, and flight simulation curves obtained with the conventional curve comparison, the curve with the real flight in the optimization of the more dynamic approaches, the final results will be optimized on the test flight simulator and verification.
