Direct Lift Control of Aircraft Based on Adaptive Fuzzy Dynamic Inverse

In order to deal with the problem of direct lift control of aircraft, an adaptive fuzzy dynamic inverse controller is designed. The dynamic inverse controller is used to realize the direct lift control of the aircraft. The fuzzy controller is used to dynamically adjust the parameters of the PID controller to improve the dynamic characteristics and robustness of the aircraft control system. In the initial parameter optimization process of the adaptive fuzzy controller, the ITAE performance index is improved, and the forward error integral term is introduced to add the constraint on the system steady-state error. Through the simulation experiments of simple direct lift control mode and vertical translation control mode, it is found that the fuzzy dynamic inverse controller designed in this paper can achieve direct lift control with certain robustness. And by comparing the simulation results of fuzzy dynamic inverse controller and single dynamic inverse controller, it is found that the dynamic performance of fuzzy dynamic inverse controller is better than that of single dynamic inverse controller.
