| 摘 要： | 利用递阶，分散的控制思想，将直升机对象划分为三个具有独立功能，便于建模的子系统，即直升机，旋翼，发动机子系统，再在各子系统模型基础上根据各子系统间的耦合关系，建立了整个系统的模型。其中四片铰接式旋翼模型起着纽带作用，只有充分考虑机体／旋翼及发动机／旋翼间耦合关系才能建立直升机飞行／推进综合模型，仿真结果证明了建模方法的有效性，为直升机飞行／推进综合控制系统的建立奠定了基础。

| Abstract: | The model of helicopter can be divided into three independent subsystems. A liner mathematical model of the rotor system is built under the assumption that the rotor system is articulated and the blades are rigid. A simplified model of engine and a liner model of rotor's driver train are also built. The integrated simulation model of helicopter flight/propulsion system is composed of all these models by considering the coupling relation between these subsystems. The IFPC (Integrated Flight/Propulsion Control) system of helicopter can be built under this integrated model. Simulation shows good closed loop characteristics of the IFPC system. |
