摘　　要：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。This paper presents a new design of the gust alleviation control law for the large transport air- craft under vertical gust. The closed-loop control scheme was introduced in the design. On the basis of the synthesized system model including gust and aircraft, the ride quality was improved by using the nor- mal acceleration signal to generate the corrective aileron deflection signal. Meanwhile, the stability of the aircraft was maintained by moving the elevator with the pith angle rate. The flight controller parameters were optimized by a new artificial bee colony algorithm improved by invasive weed optimization. The sim- ulations show the improved algorithm is more effective than the original one, and the gust alleviation con- trol system can reduce the additional load generated by gust.
