“…Stratosphere as the peaceful layer in atmosphere has good wind condition on a yearly average [1] for airships. Various platforms [2,3] are exploited by many scientists to operate in the stratosphere beyond traditional aircraft maneuvers. Compared with traditional aircraft and spacecraft, the stratospheric airship as a lighterthan-air vehicle performs with obvious advantages in high altitude, payload capacity and long-time operation to improve the fields of scientific explorations, remote communications and real-time surveillance.…”

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.

Solar energy is the ideal power choice for long-endurance stratospheric airships. The output performance of solar array on stratospheric airship is affected by several major factors: flying latitude, flight date, airship's attitude and the temperature of solar cell, but the research on the effect of these factors on output performance is rare. This paper establishes a new simplified analytical model with thermal effects to analyze the output performance of the solar array. This model consisting of the geometric model of stratospheric airship, solar radiation model and incident solar radiation model is developed using MATLAB computer program. Based on this model, the effects of the major factors on the output performance of the solar array are investigated expediently and easily. In the course of the research, the output power of solar array is calculated for five airship's latitudes of 0°, 15°, 30°, 45° and 60°, four special dates and different attitudes of five pitch angles and four yaw angles. The effect of these factors on output performance is discussed in detail. The results are helpful for solving the energy problem of the long endurance airship and planning the airline.

This paper is devoted to introduce a novel method of the operational matrix of integration for Legendre wavelets in order to predict the thermal behavior of stratospheric balloons on float at high altitude in the stratosphere. Radiative and convective heat transfer models are also developed to calculate absorption and emission heat of the balloon film and lifting gas within the balloon. Thermal equilibrium equations (TEE) for the balloon system at daytime and nighttime are shown to predict the thermal behavior of stratospheric balloons. The properties of Legendre wavelets are used to reduce the TEE to a nonlinear system of algebraic equations which is solved by using a suitable numerical method. The approximations of the thermal behavior of the balloon film and lifting gas within the balloon are derived. The diurnal variations of the film and lifting gas temperature at float conditions are investigated, and the efficiency of the proposed method is also confirmed.
