Anti-stochastic disturbance control of airship

Due to their long endurance and low energy consumption, airships are frequently utilized in both high-altitude and low-altitude missions. Studying the airship's anti-stochastic disturbance control is essential since it operates in a complex environment and is frequently impacted by random interference like airflow. Based on the theory of stochastic systems, this paper considers the influence of stochastic disturbance term in the dynamic modeling of stochastic systems. Then, based on the backstepping method, adaptive technique and Lyapunov stability analysis theory, a robust controller against stochastic disturbance is designed. The simulation results demonstrate that the developed controller can quickly steer the airship to the trial site and hover with the desired attitude in the presence of stochastic airflow disturbance.
