摘要
为保障多操纵面飞行器的安全性,提升飞行性能,提出了一种基于自适应控制分配的新型飞行控制方法。首先,阐述了用非线性动态逆设计多层飞行控制律的思想;然后,将与操纵效率相关的模糊罚函数引入到二次规划动态控制分配方法中,使控制分配的优化方向对于操纵效率的变化具有自适应能力,形成了自适应动态控制分配算法;最后,通过无故障三轴姿态控制仿真和故障存在情况对比仿真,验证了该方法的有效性和优越性。
Aiming at ensuring safety and improving flight performance of flight vehicle with multiple control surfaces,a new flight control method based on adaptive control allocation algorithm is proposed.Firstly,the non-linear dynamic inverse flight control method is introduced.Secondly,the adaptive dynamic control allocation is obtained by introducing fuzzy penalty function related to control surfaces efficiency into normal constrained quadratic programming.Finally,the simulation results with servo failures and without servo failures show the validity and superiority of the proposed method.
