TL;DR: In this article, a backstepping sliding-mode control approach is proposed to develop the positioning controller for an autonomous airship in the presence of model uncertainties and external disturbances, which provides the flexibility to treat nonlinear terms and guarantee the stability of a closed-loop system.

TL;DR: In this paper, a new attitude control approach for an UAV using the variable structure control theory, with a particular focus on the parameter uncertainty and external disturbance, is proposed, and the attitude controller is designed by use of double loop scheme, the outer loop and the inner loop which both track the command attitude angles and angular velocities.

TL;DR: In this paper, an adaptive fuzzy sliding mode control (AFSMC) approach is proposed for a robotic airship, and the global stability of the closed-loop system is proved by using the Lyapunov stability theorem.

TL;DR: In this paper, a control method for the flight path of an airship on the stratosphere is presented, which consists of the following steps: firstly, giving out an instruction flight path, secondly calculating an error margin e between the induction flight path and the actual flight path; thirdly, selecting a sliding mode surface s and a reaching law, designing sliding mode control law and calculating the system control amount tau; and fourthly, designing a fuzzy controller with the slidingmode surface s as an input of the fuzzy controller and with a control parameter as an output of the
