Observer-Based Adaptive Control for a Coupled PDE–ODE System of a Flexible Wing

IEEE Transactions on Systems, Man, and Cybernetics: Systems
This article proposes an adaptive observer-based control to address the PDE–ODE coupled system of a flexible wing, where external disturbances and references have unknown frequencies, amplitudes, and phases. An exosystem is defined for the above signals,

Adaptive Dynamic Programming-Based Intelligent Finite-Time Flexible SMC for Stabilizing Fractional-Order Four-Wing Chaotic Systems

Mathematics
Fractional-order four-wing (FO 4-wing) systems are of significant importance due to their complex dynamics and wide-ranging applications in secure communications, encryption, and nonlinear circuit design, making their control and stabilization a critical

Altitude control for flexible wing unmanned aerial vehicle based on active disturbance rejection control and feedforward compensation

International Journal of Robust and Nonlinear Control, 2019
For achieving the accurate trajectory tracking of the flexible wing unmanned aerial vehicle in the complicated missions, especially the vertical component, a feedforward compensation unit–based active disturbance rejection control (ADRC) is proposed.

An Online Reinforcement Learning Wing-Tracking Mechanism for Flexible Wing Aircraft

International Symposium on Robotic and Sensors Environments, 2019
Flexible wing aircraft are gaining an increasing interest due to their salient features, such as inexpensive market price, low-cost operation, in-flight robustness, multi-purpose use, and their ability to operate with very little infrastructure.

Adaptive fault-tolerant boundary vibration control for a flexible aircraft wing against actuator and sensor faults

Journal of Vibration and Control, 2021
The vibration control problem was investigated in this study in the presence of unknown loss of actuator effectiveness fault and loss of sensor effectiveness fault in a flexible aircraft wing system. A series of partial differential equations was used as
