平流层飞艇上升段高度控制方案

摘要

为更好地进行平流层飞艇上升段控制并提高上升速度,建立飞艇三自由度纵向动力学方程.从理论上分析了副气囊单一控制存在上升速度较慢的问题,提出了在飞艇上升段采用螺旋桨推力+动升力+静升力的复合控制方案,分别对2种方案设计了控制器,并通过数字仿真验证了在飞艇上升段采用复合控制方案的合理性.%In order to better control stratospheric airship ascending stage and accelerate its ascending speed, construct the stratospheric airship 3-dimensional portrait dynamics equation. After analyze the problem of slow ascending speed of the semi-control scheme of ballonets, a new control scheme that depend on static lift, airscrew thrust and aerodynamic lift to ascend in the ascending stage is presented. According to these two schemes, the comparison controller is designed. The feasibility of the composite control scheme is tested by computer simulation.
