Abstract :
According to attitude control of a hypersonic gliding vehicle, a decoupling control approach based on NESO is proposed. Decoupling control is realized through the decentralized control theory. The system coupling terms and uncertainties are estimated by NESO and added into the control law for compensation. Theoretical analysis proves that the tracking errors of the closed-loop system are consistently bounded. Simulations are carried on through the hypersonic gliding vehicle model comparing the proposed method and the traditional sub-channel control method. The results show that the tracking effectiveness of the proposed method is better and impact caused by coupling and uncertainties is eliminated.
