摘要
采用控制分配方法,进行飞机垂直阵风减缓控制律设计。垂直阵风减缓控制律设计的目标是由操纵面产生直接升力抵消阵风引起的过载变化。控制分配方法用来解决如何由多操纵面来产生所需的力和力矩的问题。在阵风减缓控制律设计中,采用控制分配方法计算出为消除过载扰动量所需的操纵面增量,从而直接实现阵风减缓控制。仿真表明,设计的阵风减缓控制律对于垂直离散突风和紊流干扰均具有很好的控制效果,并且对于建模误差具有一定的鲁棒性。
Control allocation method is used in vertical gust alleviation system design.The purpose of the vertical gust alleviation control law is to generate direct lift force to restrain the effects of the disturb.Control allocation method solve the problem of how to general expected forces and moments using multiple control surfaces.In the designing of gust alleviation control law,control allocation method is used in calculating the necessary increment of the control surface deflection to counteract the normal load increment caused by the gust.Simulation result proved that the gust alleviation control law designed is effective when discrete wind gust and turbulence appeared,and the control law is robustness to the modeling error.
