多舵面大型民机阵风减缓系统设计

Gust alleviation control system design of large civil aircraft based on multiple control surfaces

提出用多块对称偏转的扰流片和副翼构成飞机的多舵面操作模型,采用开闭环控制相结合的控制方案,并用LQG方法实现控制律的设计和仿真,设计了一种切实可行的民机阵风减缓控制系统。仿真结果表明,所设计的阵风载荷减缓控制器能有效减缓阵风引起的飞机法向过载,实现阵风减缓。

A method is designed for a gust alleviation control system of large civil aircraft based on multiple control surfaces in this paper. The model of multi-rudders manipulation is constituted by the spoilers and ailerons with symmetrical deflection blocks, and combined the open-loop control and close-loop control scheme. And meth＇ ods of the LQG realize the design and simulation of the control law. The simulation results verify the gust alleviation control system is feasible.
