Model construction and simulation of fixed height flight controller for ornithopter
Aiming at the problem of poor adaptability of traditional flight control algorithms and complex aerodynamic characteristics of ornithopter,a fixed height flight controller based on fuzzy adaptive PID algorithm for new bionic ornithopter was proposed.A new type of flapping wing with simple structure was designed by using complex vector method,and the flight kinematics model of ornithopter at fixed height was established by kinematic simulation and computational fluid dynamics simulation.The control effect of the fuzzy adaptive PID controller designed in this paper on this model was tested by simulation,and compared with the controller based on the traditional algorithms.The experimental results show that the as-proposed fuzzy adaptive PID controller has better response characteristics and adaptability than the traditional controller.
