Iterative Learning-Based Path Optimization for Repetitive Path Planning, With Application to 3-D Crosswind Flight of Airborne Wind Energy Systems
IEEE Transactions on Control Systems Technology, 1–13.
author keywords: Adaptation models; Optimization; Performance analysis; Aerodynamics; Wind energy; Geometry; Iterative learning control; Airborne wind energy (AWE); emerging control applications; iterative learning control (ILC); path optimization
TL;DR:
This paper proposes two candidate update laws, both of which parallel the mathematical structure of common iterative learning control (ILC) update laws but replace the tracking-dependent terms with terms based on the performance index, and applies this formulation to the iterative crosswind path optimization of an AWE system, where the goal is to maximize the average power output over a figure-8 path.

Trajectory tracking of a knife-edge on a flat surface
2019 18th European Control Conference (ECC). Presented at the 2019 18th European Control Conference (ECC).

Programmable active kirigami metasheets with more freedom of actuation
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 116(52), 26407–26413.
author keywords: kirigami; metamaterial; thermal actuation; programmable machine; polarization switch
TL;DR:
A universal design of implementing folds to reconstruct sole-cuts–based metamaterials is demonstrated and it is shown that the supplemented folds not only enrich the structural reconfiguration beyond sole cuts but also enable more DOFs in actuating the kirigami metasheets into 3 dimensions (3D) in response to environmental temperature.
