摘要

摘要: 为了确保变体飞机在变体过程中的飞行稳定性，提出了一种并行修正控制器设计方案.采用backstepping方法进行标称控制器设计，提供基本的飞行稳定性和跟踪性能.使用雅可比线性化方法对变体飞机非线性方程进行线性化得到线性化模型，采用基于指令滤波器的滚动时域优化（RHO，Receding Horizon Optimal）方法进行修正控制器设计.在有限时域区间内实时解算修正控制量，对标称控制器进行补偿.从航迹角控制系统仿真结果可以看出，航迹角能够较好地跟踪指令信号，基本不受变体过程的影响，飞行控制系统满足实时性和鲁棒性的要求.

Abstract: In order to ensure the flight stability of morphing aircraft in the morphing process, a parallel retrofit controller was proposed. The nominal controller was designed by the backstepping technique, which was used to provide the basic flight stability as well as the tracking performance. The nonlinear dynamic equations of the morphing aircraft were linearized by the Jacobian linearization approach, and a linearized model was obtained. The retrofit controller was designed by the receding horizon optimal (RHO) algorithm based on the command filter. The retrofit value was calculated within a finite horizon in real-time to compensate for the nominal controller. The simulation results of the flight path angle control system show that the flight path angle can track the command signal regardless of morphing process, and the flight control system satisfies the requirements of real-time and robustness.
