“…Different with the general vehicles such as aircraft and robot, the additional fluid inertia force and the elastic deformation of balloon should be taken consideration due to the huge flexible structure during modeling (Mueller and Paluzaek, 2004). Apart from the traditional modeling methods based on the Newton-Euler equations (Schmidt, 2007), some new methods based on semidirect product reduction theory (Azouz et al, 2002) and Updated Lagrangian model (Azinheira et al, 2002) are presented. Bijker and Steyn (2008) model the airship through traditional methods, and estimate the model parameters with a Kalman filter.…”

“…Furthermore, dynamic inversion technology [13,14] and backstepping technology [15,16] have been applied to the autonomous airship based on its nonlinear model. In addition to stabilization control, the trajectory tracking [17,18] and pathfollowing control [19] driving the position of airship to a desired time-varying trajectory should be studied, and the airship can be controlled to perform the cruising flight [20][21][22] and station-keeping tasks [23][24][25]. For the cruising flight task, a straight-line trajectory can be designed, and the trajectory tracking controller achieves line tracking to perform the monitoring and transporting applications simultaneously.…”

A nonlinear adaptive trajectory tracking control strategy is proposed for a fully actuated stratospheric airship subject to uncertain mass and inertia parameters. Based on the stratospheric airship trajectory tracking model, a non-certainty equivalence adaptive control approach is adopted to estimate the uncertain parameters since its excellently attractive property of the immersion and invariance manifold condition.The key idea involves a new filter construction for the regressor terms in the airship dynamics that enables the establishment of a stabilizing mechanism within the adaption process for uncertain parameters. It is proved that trajectory tracking errors asymptotically converge to zero within the Lyapunov framework. Numerical simulations are presented to demonstrate the performance of the proposed controller.

“…Circling control that forces the airships tracking a circle trajectory is a special kind of motion control, and it can be transformed into trajectory tracking or path following problem. For hovering control, the stabilization control of airships, linear control methods have been utilized 17,18 and backstepping control approach has been used. 19 These controllers are based on the linearized model of airships, and they are effective only around the equilibrium state.…”

A novel hovering control methodology for a stratospheric airship is presented by using path following approach in the presence of unknown wind. First, the dynamic model of the airship used for controller design is introduced. Then, the hovering control is transformed into the path following control by expressing the wind field in the state equation, which avoids the difficulty of guaranteeing system stability in strong wind for other stabilization methods. The designed control system finally possesses a cascaded structure which consists of a guidance loop, an attitude control loop and a velocity control loop. An observer is proposed based on the vehicle kinematics to estimate the unknown wind field. Stability analysis shows that the controlled closed-loop system is globally asymptotically stable and the sway velocity which cannot be directly controlled converges to zero. Simulation results for the stratospheric airship to hovering in a certain position are illustrated to verify effectiveness of the proposed method.
