According to the characteristics of the stratospheric satellite tether, consider the tether's own gravity and flexibility, build the model of the tether by using piecewise analysis and iterative calculation method. Then, combined with the overpressure balloon and the pneumatic sail, establish a meridional motion model of the "balloon -tether -pneumatic sail" flexible multi-body flight system. Based on the fuzzy control method, according to the deviation of the north and south direction's expectations position and actual position of the balloon, design the control system of the pneumatic sail by using the self-tuning fuzzy PID control method. Simulation results have shown that the pneumatic sail using this method can achieve the meridional orbit steady control of the stratospheric satellite in both steady wind field and unsteady wind field.

“…Near space is above where a commercial airliner flies but below the realm of an orbiting satellite. Since the meteorological condition in near space is stable and the electromagnetic environment there isn't as harsh as in space, the area has been exploited by near space vehicles for communications, Earth observation, as well as military surveillance during last decades [1] . Recently more and more attention has been paid to the research and development of near space vehicles among the related community all over the world due to the rapid progress of science and technology corresponding to near space.…”

Research on the visual simulation system of a stratospheric satellite's trajectory control

et al. 2011

A stratospheric satellite, which is a new type of low-cost and low-energy-consumption spacecraft, can be controlled by a stratosail to orbit around the Earth's stratosphere from east to west at the height of 35 km. This paper researches on the visual simulation system of the stratospheric satellite's trajectory control. First, based on the more complete investigation of the characteristics of stratospheric environment and stratospheric winds, the trajectory control method of the stratospheric satellite is proposed, and then the components of the stratospheric satellite and their functions are given: a super-pressure helium balloon is used to balance the gravity, a stratosail to control the trajectory, and a 15km-long tether to connect the balloon and the stratosail to make them located in different wind strata. Second, the dynamic models of the balloon and stratosail are derived more compactly due to the appropriate options and definitions of various coordinate systems. After that, various simulations are carried out in scenarios of different wind conditions. Third, according to the dynamic models, the trajectory control scheme is proposed. In the end, the Creator and Vega Prime software platforms are applied to develop a visual simulation system for the trajectory control of the stratospheric satellite using the results of numerical simulations as input. The results of the visual simulation system show that the stratosail can be used to control the trajectory of stratospheric satellites precisely. Moreover, in the presence of wind disturbances the stratospheric satellite can still be controlled by the stratosail to fly from east to west along the predefined trajectory, namely, the control of the south-north direction is stable. Furthermore, through the visual simulation system, the trajectory control can be demonstrated visually, which means the control performance can be evaluated more intuitively.

“…Google has launched a project named Project Loon last year, which is aimed to provide WiFi service in remote areas of the world [1]. The traditional stratospheric satellite developed by the Global Aerospace Corporation of NASA consists of a supper-pressure helium balloon, a load gondola, a tether and a stratosail [2]. With the expanding of its application fields, such as emergency communication, dynamic network organizing and so on, stratospheric satellite is demand to respond more rapidly.…”

“…To model the stratospheric satellite, the reference frames should be defined first. The earth reference frame (ERF) and the body reference frame (BRF) used in this paper can be referred to [2]. The satellite position and attitude are described by the center of volume (CV) O position p = (x, y, z) T and Euler angles Θ = (φ, θ, ψ) T in ERF.…”

This paper addresses the path following of a stratospheric satellite with propulsion systems, which is effective to realize orbit keeping and transfer. An algorithm for accurate path following of stratospheric satellites is proposed based on the theories of vector field and sliding mode control. Firstly, the dynamic model of the satellite propulsion system is presented, in which a 6 degree-of-freedom (6-DOF) stratospheric satellite model is introduced. Secondly, the control algorithm is proposed, which includes vector-field-based guidance laws to guide the satellite towards the desired path, sliding mode controllers to reduce path-following errors into an acceptable range and a forward velocity controller to maintain a constant velocity. Finally, simulation results demonstrate the effectiveness of the proposed control algorithm. 5370 978-1-4799-7016-2/15/$31.00 c 2015 IEEEThis paper is organized as follows. The model of the stratospheric satellite used throughout this paper is presented in Section 2. In Section 3 the path-following controllers are designed. In section 4, a simple forward velocity controller is added to the control strategy. Simulation results are given in Section 5. In the last section, a brief summary is concluded and the future work is indicated. MODELINGAs is shown in Figure 1, the stratospheric satellite studied in this paper consists a helium balloon and a truss below. The avionics system, power system and payloads are equipped in a gondola fixed below the balloon, while the solar-cell panels are attached on the surface of balloon to supply electricity. A pair of tandem vector propulsion systems, which could supply the driving force between -90 and 90 degree around their vertical axes, are installed on both ends of the truss respectively. Thus, the propellers provide main propulsive force and steering torque. *9 [ \ 2 J 2 J \ J [ J ]
