| 英文摘要 |
| To implement the flight of stratospheric satellites along latitudinal orbits in atmospheric circulation, the
longitudinal trajectories of the stratospheric satellite must be controlled. First, the 6-DOF dynamic model of a stratospheric
satellite is established based on the Lagrange dynamic formulation for the longitudinal trajectory control design. Because
the input/output linearization method is not applicable to this model, the whole system is decomposed into three cascaded
subsystems based on the flight-control mechanism of the satellite, i.e. the rudder controls the stratosail, the stratosail
supports the tether, and the tether drags the balloon; and then, three separate controllers are developed for each subsystems
to achieve the trajectory control of the balloon via the rudder. Simulation results demonstrate the effectiveness of the
proposed controllers. |
