    Abstract:

    The near-space airship provides a unique and promising platform for telecommunication, broadcasting relays, surveillance, and scientific exploration. A key control technical challenge for a near-space airship is station keeping, the ability to remain fixed over a geo-location. A fuzzy variable structure control approach for an airship is proposed. First, problem formulation of an airship’s attitude control was derived. Second, the attitude control system was designed by using the variable structure control theory, and a fuzzy system was used to turn the control gains for better performance of eliminating chattering. Finally, simulation results demonstrate the effectiveness and robustness of the proposed control approach in the presence of parameter uncertainties.
