基于能量方法的飞行控制系统设计与仿真

Design and Simulation of Energy-based Flight Control System

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。文中研究了基于能量方法的飞行控制系统的设计方法,建立了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,并以某型飞机为研究对象进行了综合仿真,仿真结果表明:基于能量方法的控制系统实现了纵向飞行轨迹控制与速度控制之间的解耦。

■energy com■ is a new concept for the integrated inght/propu■sion control of a■.■ased on control- ling 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.In this paper,the design method of the energy-based flight control system is discussed.The aircraft point-mass energy movement model is established based on its inner longitudinal atti- tude control loop and engine thrust control loop.Finally a typical energy-based flight control system is designed for an aircraft model,and simulation results show that it decouples the vertical flight path and speed control.
