摘　　要：飞 推综合控制考虑飞机和发动机之间的性能耦合,彼此进行信息的综合,从整体最优的设计出发,充分发挥飞机和发动机的性能潜力,提高飞机性能。为了验证飞 推综合控制模式的性能效益,提出并开展了该控制模式在亚音速下的半物理仿真试验的研究,结果表明:在平飞加速工况下,采用最大推力模式,可提高发动机推力约9%;在亚音速巡航时,采用最小油耗模式,可节省单位油耗约1 5%。An integrated flight/propulsion control algorithm offers significant performance improvements using Linear Programming to compute a set of adjustments to the normal control settings. The integrated flight/propulsion control system is developed, and is used in simulation of hardware-in-loop with the two optimization modes: maximum thrust mode and minimum fuel consumption mode. Test results presented here demonstrate that during accelerating flight at constant altitude thrust increases up to approximately 9 percent in the maximum thrust mode, and at subsonic cruise specific fuel consumption decreases up to 1.5 percent in the minimum fuel consumption mode.
