摘要
最优航迹跟踪要求飞机的实际飞行航迹与理想航迹的偏差最小 ,但若采用按偏差的最优控制方法 ,会造成控制变量的剧烈震荡 .为了解决控制变量的剧烈震荡问题 ,提出了一种新的偏差 微分综合控制方法 .通过对参考航迹的跟踪验证 ,表明该方法有效地解决了控制变量最优解的振荡问题 。
Minimizing the tracking deviation between the real path and the referenced path can produce optimal following path, but it will bring a considerable oscillation of optimal control variables. In order to alleviate the considerable oscillation, an integrated control method that combines the deviation with its differential was presented. The numerical application of the integrated control method demonstrates that the proposed method is effective and valid with respect to the possible oscillation of optimal control variables. Consequently, the precision performance of the flight path following is further realized.
