摘要
飞机总能量控制是一种全新的综合飞行/推力控制技术,从控制飞机总能量的变化与分配出发,全面解决纵向飞行轨迹控制与速度控制之间的耦合问题;进而建立起一体化的综合飞行控制系统。用多变量系统解耦控制理论研究了这种控制系统,首先分析了总能量控制的基本思想,建立起包含飞机纵向姿态控制回路和发动机推力控制回路的飞机质点能量运动模型,然后利用输出反馈和V规范型前馈解耦策略,对此系统进行解耦分析,设计出能实现飞行轨迹与速度间解耦控制的总能量控制律,并确定出系统的设计条件;最后以波音(Boeing)707飞机为对象,进行了具体的系统设计。
Total energy control is a new concept for the integrated flight / propulsion control of aircraft. Based on controlling the amount of aircraft total energy and its distribution, it decouples the vertical flight path and speed control, and further establishes a unified flight control system. This paper studies this control technique with the decoupling control principle of multi-variable system. First, the basic concept and principle of total energy control system (TECS) is analyzed, and the aircraft point-mass energy movement model is established based on its inner longitudinal attitude control loop and engine thrust control loop. Then, with output feedback control and fore-feed V-canonical decoupling structure, the TECS is analyzed, the control law which can decouple the vertical flight path and speed control of aircraft is designed, and the system design criteria are determined. Finally, a typical TECS is designed for a Boeing- 707 transport aircraft model, and satisfactory simulation results are obtained.
