Variational Robust Kalman Filters: A Unified Framework
Shilei Li, Dawei Shi, Hao Yu +1
Robustness and adaptivity are two competing objectives in Kalman filters (KF). Robustness involves temporarily inflating prior estimates of noise covariances, while adaptivity upda…
Event-triggered Dual Gradient Tracking for Distributed Resource Allocation
Xiayan Xu, Xiaomeng Chen, Dawei Shi +1
High communication costs create a major bottleneck for distributed resource allocation over unbalanced directed networks. Conventional dual gradient tracking methods, while effecti…
Improved Extended Kalman Filter-Based Disturbance Observers for Exoskeletons
Shilei Li, Dawei Shi, Makoto Iwasaki +3
The nominal performance of mechanical systems is often degraded by unknown disturbances. A two-degree-of-freedom control structure can decouple nominal performance from disturbance…
Online Coreset Selection for Learning Dynamic Systems
Jingyuan Li, Dawei Shi, Ling Shi
With the increasing availability of streaming data in dynamic systems, a critical challenge in data-driven modeling for control is how to efficiently select informative data to cha…
Enhanced Superconductivity and Mixed-dimensional Behaviour in Infinite-layer Samarium Nickelate Thin Films
Mingwei Yang, Heng Wang, Jiayin Tang +24
Rare-earth infinite-layer nickelates represent an emerging class of unconventional superconductors, with materials synthesis largely limited to early lanthanide compounds. Here, we…
