| 摘 要： | 研究了飞/推综合控制系统的在线优化实时性问题。提出将机载发动机复合模型与序列二次规划(Sequential quadratic programming,SQP)算法结合应用于飞/推综合优化控制的策略。首先,设计适用于全包线范围并可大幅度缩短优化时间的发动机稳态复合模型,然后基于SQP算法将该模型应用到发动机性能寻优控制中,包括最大推力和最小油耗优化模式,从而更加有效地完成各种不同的飞行任务。通过飞机巡航、平飞加速等仿真实验,表明了该优化控制方案能够在具有较好优化效果的前提下,明显提高飞/推综合控制系统的优化实时性。

| Abstract: | The real-time capability of integrated flight/propulsion optimal control(IFPOC)is studied.An application is proposed for IFPOC by combining the onboard hybrid aero-engine model with sequential quadratic programming(SQP).Firstly,a steady-state hybrid aero-engine model is designed in the whole flight envelope with a dramatic enhancement of real-time capability.Secondly,the aero-engine performance seeking control including the maximum thrust mode and the minimum fuel-consumption mode is performed by SQP.Finally,digital simulations for cruise and accelerating flight are carried out.Results show that the proposed method improves real-time capability considerably with satisfactory effectiveness of optimization. |
