摘要
针对小型无人直升机重量轻、速度小,受风场扰动影响大的问题,提出了一种基于前飞状态的抗风策略;首先,分析了风对无人直升机的影响;其次,在考虑尾桨配平误差的前提下,实现了基于侧航法的横侧向抗风策略和以空速保持为核心的纵向抗风策略;仿真结果表明,样例无人直升机在不同风场下飞行时,均能保证气动特性不发生变化,对飞行安全具有非常重要的意义。
Abstract: To cope with the problem of wind disturbance to an unmanned helicopter in forward flight, this article proposes a wind resist- ant control scheme. Firstly, the effect of the wind on unmanned helicopter is analysed. Then the lateral wind--resistant scheme which based on crabbed flight and the longitudinal wind--resistant scheme which based on airspeed control are carried out, with considering the trim error of the pedal. The simulation indicates that the scheme can keep the aerodynamic characteristics of the unmanned helicopter under different wind conditions, which plays an important role in flight safety.
