Lateral Oscillation of Small UAVs in High-Speed Flight

针对小型无人机在高速飞行时的横向振荡问题,从飞行控制系统原理出发分析了造成振荡的各类因素,重点分析了飞控参数和系统延时等影响因素,并进行了仿真验证,确定出振荡的原因。通过采取在高速飞行时对飞控参数增加调节系数和减小系统延时等措施,以仿真和实际飞行的方式验证了改进措施的有效性,较好地解决了横向振荡问题。

To solve the problem of lateral oscillation of small UAVs in high-speed flight,this paper analyzes all kinds of factors causing oscillation from the perspective of the principle of the flight control system,focuses on such factors as flight control parameters and system delay,and conducts simulation verification to determine the cause of the oscillation.By adopting the measures of adding an adjusting coefficient to flight control parameters and reducing the system delay in high-speed flight,the effectiveness of the improvements is verified by simulation and actual flight,and the problem of lateral oscillation is solved.
