Covariance-Regulated Recursive Koopman Learning for Nonlinear Systems with Uncertain Time-Varying Dynamics
Weibin Gu, Chen Yang, Lu Shi +1
Offline models for autonomous robots often fail under time-varying dynamics outside their training distribution. Koopman operator theory offers a linear representation of nonlinear…

Koopman Identification of Nonlinear Systems via Reservoir Liftings
Weibin Gu, Chen Yang, Lu Shi
Learning tractable linear representations of nonlinear dynamical systems via Koopman operator theory is often hindered by dictionary selection, temporal memory encoding, and numeri…

A 26-Gram Tailless Butterfly-Inspired Flapping-Wing Robot with Onboard Attitude Control
Weibin Gu, Chenrui Feng, Lian Liu +7
Butterfly-inspired flapping-wing robots use broad compliant wings and low-frequency actuation, but pronounced wingbeat-synchronous body dynamics and time-varying inertia complicate…
