无人机垂直突风风扰响应控制指令设计

Instruction design of wind disturbance response of unmanned aerial vehicle under the vertical gust

针对无人机(UAV)在风场中进行飞行试验时其经济性与安全性不足的特点,提出了一种在试飞过程中通过嵌入式输入信号来激励UAV,使UAV产生能够模拟风扰的运动响应的方法。建立了基于PID控制方法的嵌入式指令设计方法,并以某型UAV为例,通过数值仿真,进行了模拟垂直突风的嵌入式指令设计。仿真结果表明,嵌入式指令可较好地模拟UAV的风扰响应,该方法对于UAV的飞行试验评定技术具有很好的参考价值。

For this reason that the economy and safety of conventional UAV flight test under wind field are insufficient,the paper proposes a method to simulate the motion response of UAV under wind disturbance by designing embedded instruction which is applied on control surface directly based on PID controller.As an example,the embedded instruction which simulates the response of an UAV under vertical gust was proposed.The results show that response of UAV under embedded instruction is similar to the response under wind field.The research method is of reference value to the flight test evaluation technologies.
