Physics Parameter Identification of Annular Tuned Liquid Damper for the Structure‐Damper‐Coupled System Using a Mechanics‐Enhanced SSI Method

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Tuned liquid damper (TLD) is one of the main technologies for passive control. The fundamental modal parameters of a TLD contain natural frequency and damping ratio, which are primarily related to the liquid height in the TLD device. Although the liquid height of the TLD is calibrated before installation, it is still necessary to identify the physics ...

Anti‐sloshing control: Flatness‐based trajectory planning and tracking control with an integrated extended state observer

IET Cyber-Systems and Robotics, Volume 6, Issue 3, September 2024.
Abstract The phenomenon of sloshing causes a significantly negative impact on a wide range of industries. A time‐optimal flatness‐based trajectory planning and Lyapunov‐based model predictive control (LMPC) is proposed for trajectory tracking of a transmitting cylindrical container filled with liquid.
