Aircraft control with the use of model reference adaptive control

Abstract

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.

Robust fault-tolerant preview control for automatic landing of carrier-based aircraft

“…In Zhen et al (2019a), the adaptive super-twisting control was applied to design ACLS for aircraft with model uncertainties, deck motion and airwake disturbance. The model reference adaptive control was used to design the control law (Zhen et al, 2019b;Kopecki, 2021). The sliding mode control was used to design the ACLS (Duan et al, 2022a;2022b) due to its insensitivity to the external varying environment.…”

Automatic carrier landing for UAV based on integrated disturbance observer and fault-tolerant control

“…The fault-tolerant control is necessary to maintain an acceptable landing performance under these faults. Research is mainly focused on actuator faults (Kopecki, 2021; Liu et al , 2022), sensor faults (Unal, 2021) and structural faults (Wang et al , 2016). Very little research studies the fault-tolerant control for UAV automatic carrier landing; most people are paying close attention to the fault-tolerant control for spacecraft (Lu et al , 2022), UAV attitude tracking (Yu et al , 2022) and robotic manipulators (Zhang et al , 2022a, 2022b).…”
