武装直升机横航向解耦控制研究

应用现代控制理论中的特征结构配置法，设计了武装直升机横航向增控增稳控制系统，并通过特征向量的选型使横航向两通道实现解耦，考虑舵回路后，利用增广的模型矩阵，通过特征配置求出输出反馈控制律，进而与指令模型，机械通道传动比一起构成解耦控制的系统结构图，数字仿真结果表明，系统具有良好的解耦控制效果和闭环特性。

A Research on the Lateral Directional Decoupling Control of Armed Helicopter

The eigenstructure assignment methods of modern control theory are applied to design the lateral directional channel of armed helicopter SCAS (Stability and Control Augmentation System), and the lateral directional channel decoupling is reached through eigenvector shaping. In consideration of rudder loops, the matrix augmentation model is used to obtain the output feedback control rule through eigenvalue assignment. And the structure diagram of decoupling control system is made with the command model and the transmission coefficient of mechanization channel. The results of simulation are consistent with the requirement of decoupling control system, and the closed loop characteristics are excellent.
