针对飞翼布局无人操纵能力不足的特点,提出了结合流体矢量涡轮发动机(FTV-E)控制技术控制策略。本文设计了内环线性化解耦以消除已知不利的耦合项,外环反步跟踪算法进行航迹跟踪,并采用粒子群补偿器补偿各种扰动和不可建模的耦合项的控制方案。文中证明了该控制结构的稳定性。同传统反步控制方法相比,本控制器增加了内环解耦结构。不同与传统的动态逆解耦控制方法,本文在控制结构中保留气动阻尼项,使得线性化后的系统为弱非线性系统。该结构不仅可以降低外环控制器设计的保守性,而且便于工程实现。仿真结果显示,该控制方案是有效的。
In view of the characteristics of the unmanned controllability of the flying wing layout, a control strategy based on FTV-E control technology is proposed. In this paper, the inner loop linearization decoupling is designed to eliminate the known adverse coupling term and the outer loop backstepping algorithm to track the trajectory. The particle swarm compensator is used to compensate the control schemes of various perturbations and non-modeling coupling terms. The paper proves the stability of the control structure. Compared with the traditional backstepping control method, the controller adds an inner loop decoupling structure. Different from the traditional dynamic inverse decoupling control method, this paper retains the aerodynamic damping term in the control structure so that the linearized system is a weakly nonlinear system. The structure can not only reduce the conservative design of the outer loop controller, but also facilitate the realization of the project. Simulation results show that the control scheme is effective.
