基于模型预测的弹性飞机阵风减缓技术研究

Research on the gust alleviation technology of elastic aircraft based on model predictive control

弹性飞机受阵风影响显著,需要设计阵风减缓系统来降低阵风的不利影响。然而,阵风减缓系统受系统约束的影响会降低减缓率,严重时甚至导致系统失稳。为解决该问题,提出了基于模型预测控制的阵风减缓系统设计方法。以某弹性飞机为例,对常见的系统约束开展仿真研究。结果表明,所提方法在系统存在约束时具有更好的控制性能。

Elastic aircraft are seriously affected by gust,so a gust alleviation system should be designed to reduce the adverse effects of the gust.But this system is affected by system constraints,which could reduce gust alleviation rate,even cause the loss of control system stability.To solve this problem,a design method of gust alleviation system based on model predictive control was put forward.Take an elastic aircraft as an example,we did a simulation research on the common system constraints.The results show this method can get better control performance when the system has strong constraints.
