摘要
针对飞机地面压力加油管路系统通向油箱的管路压力脉动现象,本文提出一种新的实时主动流量控制方法。基于传统被动式蓄压器,建立其动特性方程,并提取可控参量,通过前馈及反馈技术,确定出优化控制律,对管路瞬态压力进行在线控制。同时评估了控制系统的鲁棒性,并讨论了扰动带来的不确定性对稳定性和控制精度的影响。理论研究及数字仿真结论验证了该方法的有效性。
Aimed at the pressure transient of the aircraft refueling pipeline, a new real time flow control method based on the traditional passive accumulator is presented in this paper. The dynamic characteristic equations of the inner parameters of the transient suppressor are established, and the controllable vectors are also extracted.Then with the help of feed-forward and feed-back technology,the optimal control scheme is determined. At the same time the effects of system抯 uncertainties are considered to evaluate the robustness. At last the method mentioned above is utilized to eliminate the very high transient pressure on line. The results of theoretic analysis and simulation show that it is correct and valid.
