摘　　要：舰尾流扰动是造成舰载机着舰误差的重要原因,为抑制舰尾流的影响,提高着舰精度,本文提出了一种基于模型参考模糊自适应系统(Model reference fuzzy adapting system,MRFAS)的舰载机着舰飞行控制律设计方法。以某舰载飞机为研究对象,在设计过程中,将自适应控制和模糊参数整定有机结合,构建了舰载机着舰的智能H飞行控制系统,加入不同海况下的舰尾流,对其舰尾流抑制效果以及该系统的自适应性能进行了仿真验证。结果表明,该设计方法不仅能够有效抑制舰尾流,使着舰误差精度提高约7.2%,而且可以提高跟踪理想下滑轨迹的快速性,同时利用该方法设计的飞控系统具有很强的自适应能力,从而更好地保证飞机的着舰安全。Air wake disturbance of carrier-based aircraft is an important cause for carrier landing error. For air wake rejecting and error precision increasing, a control law design method for carrier-based air- craft landing is presented based on model reference fuzzy adapting system（MRFAS）. The research ob- ject is one of certain carrier-based aircraft. In the designing process, adaptive control and fuzzy parame- ter adapting are combined, so that the intelligent/5/flight control system model of carrier-based aircraft landing is established. Meanwhile, the air wake in different sea states is also considered, which realizes the intelligent rejecting control of air wake and the adapting of parameters. Besides, the simulation re- sults of its restrain effect on air wake and the adaptive performance of this system are presented. The re- sults indicate that the new method can not only efficiently restrain the air wake, which increases the er- ror precision by about 7.2 %, but also can increase the quickness of tracking of the desirable slide track. Meanwhile, a flight control system designed by the method would be provided with strong adaptive abil- ity, so that it can ensure the safety of aircraft landing.
