摘　　要：设计了一种飞艇类新构型临近空间飞行器,能够通过具有翼型外型的气囊产生浮力和升力,在高空实现定点悬停、低速前飞,并完成一系列飞行任务。建立了飞艇飞行动力学模型,通过模糊控制器控制气囊迎角,使其适应于当前飞行状态;结合串行PID控制器,实现对位置及姿态的稳定控制,使飞艇能够在临近空间状态下实现稳定飞行。仿真结果表明,所设计的飞艇能够在较大阵风扰动情况下按照既定轨迹完成飞行任务;在12 km高度下,受盛行西风影响时仍能够完成既定的飞行任务。A new configuration near space vehicle of airship class is designed,which generates buoyancy and lift through airfoil shaped airbags,hovers at high altitude,flies forward at low speeds,and carries out a series of flight tasks.The flight dynamics model of the airship is established and the angle of attack of the airbag is controlled by a fuzzy controller,so that it can adapt to the current flight state.Combined with serial PID controller,the position and attitude of the airship are con-trolled stably,so that the airship can fly stably in the near space state.The simulation results show that this newly designed airship is capable of achieving a flight task according to the given trajectory under the condition of large gust disturbance;it even carries out the established flight tasks under the influence of prevailing westerly winds at an altitude of 12 km.
