Purpose

Indirect (fly-by-wire) control systems for general aviation aircraft and unmanned aircraft vehicles (UAV) control systems enable the decoupling of control surfaces. This method of aircraft control is different from classical approach. The purpose of the article is to show the aircraft can be controlled even if the control control surfaces are blocked.

Design/methodology/approach

The concept discussed here relies on model reference adaptive control. The approach presented requires modifications of aircraft linearized model. In this paper, an example of roll angle control is shown.

Findings

During simulations the system worked properly with control surfaces partially blocked, if the blockage appeared close to neutral position. Exemplary simulations are shown in the text.

Practical implications

The solution presented was implemented on a UAV autopilot. Hardware in the loop simulations were performed, which shows the potential of practical usage.

Originality/value

Aircraft control, as discussed in this paper, gives the possibility of aircraft control and stable flight before a fault is detected, which increases the safety level.

使用模型参考自适应控制的飞机控制

目的

通用航空和无人飞机（UAV）控制系统的间接（电传操纵）控制系统可实现控制面的解耦。这种飞机控制方法不同于经典方法。本文的目的是显示即使控制控制面被挡住也可以对飞机进行控制。

设计/方法/方法

这里讨论的概念依赖于模型参考自适应控制。提出的方法需要修改飞机线性模型。在本文中，显示了侧倾角控制的示例。

发现

在模拟过程中，如果障碍物看起来接近中性位置，则系统会正常工作，而控制面会被部分阻塞。示例性的仿真显示在文本中。

实际影响

提出的解决方案是在无人机自动驾驶仪上实施的。进行了回路中的硬件仿真，显示了实际使用的潜力。

创意/价值

如本文所述，飞机控制可在发现故障之前提供飞机控制和稳定飞行的可能性，从而提高了安全水平。
