Trajectory Tracking Control for a Three-Dimensional Flexible Wing

IEEE Transactions on Control Systems Technology, 2022
This brief mainly considers trajectory tracking and vibration suppression for a 3-D flexible wing. The dynamical model of the flexible wing is regarded as a distributed parameter system, which is described by partial differential equations and ordinary ...

Adaptive Internal Model Control for a Flexible Wing With Unsteady Aerodynamic Loads

IEEE Transactions on Cybernetics, 2023
This article proposes adaptive internal model controls for the collocated output regulation of a flexible wing, where distributed disturbances, boundary disturbances, and references are from an exactly unknown exosystem.

Robust output regulation for a flexible wing system with unknown output disturbances and references

International Journal of Robust and Nonlinear Control, 2023
For a flexible wing system, two different exosystems are used to generate unknown references and output disturbances, respectively. The wing system is further perturbed by unknown distributed and boundary disturbances that have the same frequencies to ...

Dynamical Modeling and Boundary Vibration Control of a Rigid-Flexible Wing System

IEEE/ASME transactions on mechatronics, 2020
A boundary control approach is used to control a two-link rigid-flexible wing in this article. Its design is based on the principle of bionics to improve the mobility and the flexibility of aircraft.
