Research The Flight Effect Of A320 Aircraft Based On Adaptive Control Algorithm

This dissertation mainly researches three kinds of adaptive control methods, which are adaptive inverse, fuzzy adaptive, adaptive neural network, which are used in A320 aircraft movement in the application of the simulation model. Comparing with the traditional PID control method, it is a basic research of the adaptive control use for large civil aircraft.First, a brief description of the flight control system development has made, including the development background, and the research status of the three adaptive control methods.Then, in deep research has conducted of three kinds of adaptive control algorithms,combining with A320 aircraft longitudinal flight characteristics. The three kinds of adaptive control algorithms and classical PID control algorithms are used in laboratory simulation model of aircraft movement to achieve control and simulation of the aircraft longitudinal flight.Finally, by comparing the three kinds of adaptive control and classical PID control method for controlling the vertical channel simulation results, the advantages and disadvantages of the adaptive algorithm and the traditional PID control method is analyzed in the aircraft flight control. The results show that neural network adaptive control and adaptive inverse control has an advantage in the regulation of speed on the pitch, and fuzzy adaptive and neural network adaptive has a certain advantage in immunity. Analyzed the result,although the three kinds of adaptive control algorithms have some advantage in one side,traditional PID control method is more fit for the flight control system of large civil aircraft.
