层叠结构动态逆在无人战斗机控制中的应用

Hierarchy-structured dynamic inversion in the UCAV control

无人战斗机采用翼身融合的一体化设计。这种非传统构型的布局,带来很多优点的同时也造成了飞机的静不稳定,采用线性的控制方法很难满足无人战斗机的性能要求。通过对传统的动态逆控制方法进行改进,从内回路开始保证系统的动态性能和跟踪性能,设计了层叠结构动态逆控制器。仿真结果表明,所设计的控制器实现了系统的解耦控制,并具有较强的鲁棒性。

UCAV used wing-body integration design. This non-traditional configuration could bring many advantages; however, this has resulted in the aircraft static instability. Linear control method is difficult to meet the performance of UCAV. Through the improvement of traditional dynamic inversion ontrol method, the layered structure dynamic inversion controller is designed to ensure the dynamic performance and tracking performance starting from the inner loop. The controller realizes the decoupling control and has a relatively strong robustness.
