Study on Intelligent Flight Control System Based on Genetic Algorithm and Fuzzy Logic Control

Fuzzy logic control (FLC) techniques and genetic algorithm (GA) are used to design flight control system. The self-tuning fuzzy logic controller techniques are designed. The controller uses an angle tracking error and its derivative to control surface deflection to realize tracking control. The membership functions of input/output domains and the rules of control are presented. Based on these, the fuzzy logic controller is optimized using genetic algorithm. The choice principles of the parameters of genetic algorithm are discussed. Simulational results show that the intelligent flight control system based on genetic algorithm and fuzzy logic control has good performance and potential application ability for the design of flight control system.
