Extreme Short-Term Prediction of Unmanned Surface Vessel Nonlinear Motion Under Waves

Journal of Marine Science and Engineering
Under complex hydrodynamic conditions, Unmanned Surface Vessel (USV) exhibits non-stationary and nonlinear dynamic behaviors. Extreme short-term prediction of such nonlinear motion is therefore critical for ensuring navigational safety.

Low-rank Approximation of Linear Maps

, 2018
This work provides closed-form solutions and minimal achievable errors for a large class of low-rank approximation problems in Hilbert spaces. The proposed theorem generalizes to the case of linear bounded operators and p-th Schatten norms previous ...

Adaptive Sliding Mode-Based Multi-Timescale Pitch Control for Wind Turbines Under Extreme Wind Conditions

IEEE Access
To address the multi-timescale perturbation coupling and actuator dynamic mismatch in wind power generation systems under extreme wind conditions, we propose an adaptive pitch-control strategy.

Recursive Forward-Backward EDMD: Guaranteed Algebraic Search for Koopman Invariant Subspaces

IEEE Access
The implementation of the Koopman operator on digital computers often relies on the approximation of its action on finite-dimensional function spaces. This approximation is generally done by orthogonally projecting on the subspace.

Koopman-Based Model Predictive Control of Functional Electrical Stimulation for Ankle Dorsiflexion and Plantarflexion Assistance

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Functional Electrical Stimulation (FES) can be an effective tool to augment paretic muscle function and restore normal ankle function. Our approach incorporates a real-time, data-driven Model Predictive Control (MPC) scheme built upon a Koopman operator ...
