大型飞机机动载荷减缓控制系统设计与仿真

为了有效降低飞机机翼根部弯矩和减轻结构重量,针对我国大型飞机中的机动载荷减缓控制系统进行了设计与仿真分析验证,根据实际飞机结构特点提出了一种传感器布局方案,建立了升降舵、副翼、扰流片等独立偏转的仿真分析模型,在常规控制律的基础上,基于控制分配方法进行直接升力控制,仿真结果表明：所设计的系统能够实现机动载荷的减缓,并使得...

Maneuver Load Alleviation Control System Design and Simulation for a Large Aircraft

The application of aircarft＇s Maneuver Load Control（MLC） system can reduce the structure load and weight of aircraft wings.In this paper present a MLC system is presented for the new civil aircraft in researching of China and a simulation analysis is carried out to validate the system proposed.The simulaiton mode comes out from an actual large aircrafts whose control surfaces can deflect independently and the function of MLC system is fulfilled by the layout,which is realized by controlling the distribution methods,with the reasonably arranged sensors.The simulation resualt shows that：the MLC system is effective and the the aircraft＇s overload in z direction can be reduced 21.7%.
