Abstract

A self-repairing flight control system based on neural network direct inverse control is proposed to reconfigure the control law in order to restore the control of the damaged UAV. Considering the nonlinear and coupling property of the damaged UAV system, the architecture of neural network is chosen to establish the inverse system of the damaged system for linearization and decoupling. Then PID feedback control is introduced to improve the performance of the inverse system. Theoretical analysis and simulation results show that this control system can be used to restore the control of the damaged UAV when the traditional control fails.
