摘要

基于高阶全驱动系统理论,提出了一种针对非线性横向和纵向静不稳定STT飞机模型的俯仰和偏航通道联合过载控制器。首先,建立了飞机过载的二阶全驱动系统模型,设计了飞机横向和纵向过载的最优控制方法;通过对该控制器与传统PID控制器的数学仿真验证,表明PID控制方法在具有耦合的非线性飞机中存在明显的缺点。而高阶全驱动系统理论控制方法能够更好地适应非线性和静态不稳定问题,实现飞机过载指令的稳定跟踪,并且具有更好的快速性。

Static Unstable STT Overload Control on High-order Fully Actuated System Theory
This article proposes a joint overload controller for pitch and yaw channels on the high-order fully actuated system theory for a nonlinear lateral and longitudinal static unstable STT aircraft model. Firstly, a second-order fully actuated system model for aircraft overload was derived, and an optimal control method for lateral and longitudinal overload was designed. Through mathematical simulation verification of this controller and traditional PID controller, it is shown that the PID control method has significant shortcomings in nonlinear aircraft with coupling. However, high-order fully actuated system theory control method can better adapt to nonlinear and static instability problems, achieve stable tracking of aircraft overload commands, and have better rapidity.
