摘要
突风载荷减缓是改善飞机飞行性能的一项关键技术。基于紊流探测器获得的飞机前方突风速度信息,以翼根剪力、弯矩和翼尖加速度响应为减缓指标,建立了计入控制面偏转角度和偏转速率约束的突风载荷模型预测控制方法,设计了模型预测控制器,进行了闭环系统仿真,并与参考(PID)控制作了对比。仿真结果表明,模型预测控制能够有效抑制突风载荷。
Gust load alleviation is an important technique for improving the flight qualities of aircratts. It xs assumed that the preview information on the incoming gust shape in front of the aircraft can be obtained from a Light Detecting And Ranging gust sensor. In order to alleviate the wing root shearing force, bending moment as well as the acceleration response at wing tip, a model predictive controller with control surface deflection angle and deflection rate constraints is designed. The simulation results for the closed loop system are compared with those obtained by the reference controller（PID）. It has been shown that the controller with MPC law can suppress the gust loads effectively.
