以某大型飞机为对象,在垂直阵风干扰的情况下,提出一种新的阵风减缓控制律设计方案。首先,在阵风减缓控制系统的功能实现上,采用闭环控制方案;然后,在阵风和飞机综合模型的基础上,利用法向加速度反馈驱动副翼实现载荷减缓,采用俯仰角速率偏转升降舵实现飞机的稳定控制;最后,引入杂草入侵机制改进人工蜂群算法,用改进后的算法对阵风减缓系统进行控制律参数设计。仿真结果表明,改进后的算法明显优于原始算法,提出的控制系统能够有效减缓阵风产生的附加过载。
Taking a large aircraft as an example, a new gust mitigation control law design is proposed under the condition of vertical gust disturbance. First of all, the closed-loop control scheme is adopted to realize the function of the gust reduction control system. Then, based on the gust combined with the aircraft model, the normal acceleration feedback is used to drive the aileron to reduce the load. The pitch rate is used to deflect the elevator to realize the aircraft’s Finally, the weed intrusion mechanism is introduced to improve the artificial bee colony algorithm, and the improved algorithm is used to design the control law of the gust mitigation system. The simulation results show that the improved algorithm is obviously better than the original algorithm, and the proposed control system can effectively reduce the additional overload caused by gusts.
