Fundamental Limitations of Data-Driven Control: A Statistical Decision Perspective
Jiabao He, Feiran Zhao, Yushan Li +3
Substantial research efforts have been devoted to the design of data-driven controllers; however, comparatively less is known about their statistical performance and fundamental li…
Bridging the Prediction Error Method and Subspace Identification: A Weighted Null Space Fitting Method
Jiabao He, S. Joe Qin, HÃ¥kan Hjalmarsson
Subspace identification methods (SIMs) have proven to be very useful and numerically robust for building state-space models. While most SIMs are consistent, few if any can achieve…
Weighted Null Space Fitting (WNSF): A Link between The Prediction Error Method and Subspace Identification
Jiabao He, S. Joe Qin, HÃ¥kan Hjalmarsson
Subspace identification methods (SIMs) have proven to be very useful and numerically robust for building state-space models. While most SIMs are consistent, few if any can achieve…
Preserving Topology Privacy of Network Systems by Feedback: Conditions and Distributed Design
Yushan Li, Jiabao He, Julien M. Hendrickx +1
This paper develops a feedback-based method to preserve the topology privacy of consensus protocols in network systems. The key idea is to intentionally violate topology identifiab…
Data-Driven Moving Horizon Estimators for Linear Systems with Sample Complexity Analysis
Peihu Duan, Jiabao He, Yuezu Lv +1
This paper investigates the state estimation problem for linear systems subject to Gaussian noise, where the model parameters are unknown. By formulating and solving an optimizatio…
Resistant Topology Inference in Consensus Networks: A Feedback-Based Design
Yushan Li, Jiabao He, Dimos V. Dimarogonas
Consensus networks are widely deployed in numerous civil and industrial applications. However, the process of reaching a common consensus among nodes can unintentionally reveal the…
