摘要
为实现火星飞行器动静平衡状态的平滑过渡,满足特定点平飞的巡航要求,该文分析了火星探测无人机的运行过程,建立了火星探测无人机的纵向模型。研究了火星探测无人机拉起和平飞过程的运动特性,归纳了拉起平飞过程的控制难点。采用变控制结构和变控制参数的模态切换控制方法,实现了火星探测无人机的拉起和平飞的有效控制。仿真结果表明该文方法的可行性。
Abstract
To realize the smooth transition of balance of motion and quiescence of aircrafts and satisfy the cruise requirement of level flight above specific points,the flight processes of a Mars vehicle are analyzed and a longitudinal model of the Mars vehicle is established. The motion characteristics of pull level flight processes of the Mars unmanned aerial vehicle are researched, and the control difficulties of pull level flight processes are summarized. A mode switching control method with variable control structure and control parameters is used to achieve the effective control of pull level flight processes of the Mars unmanned aerial vehicle. The simulation results show that the method proposed here is feasible.
