With the advancement of IoT technologies and the rapid expansion of cyber-physical systems, there is increasing interest in distributed state estimation, where multiple sensors col…
Distributed Unknown Input Observer Design: A Geometric Approach
Ruixuan Zhao, Guitao Yang, Thomas Parisini +1
We present a geometric approach to designing distributed unknown input observers (DUIOs) for linear time-invariant systems, where measurements are distributed across nodes and each…
Bridging Centralized and Distributed Frameworks in Unknown Input Observer Design
Ruixuan Zhao, Guitao Yang, Peng Li +1
State estimation for linear time-invariant systems with unknown inputs is a fundamental problem in various research domains. In this article, we establish conditions for the design…
Distributed Unknown Input Observer Design with Relaxed Conditions: Theory and Application to Vehicle Platooning
Ruixuan Zhao, Guitao Yang, Thomas Parisini +1
Designing observers for linear systems with both known and unknown inputs is an important problem in several research contexts, for example, fault diagnosis and fault-tolerant cont…
On the Output Redundancy of LTI Systems: A Geometric Approach with Application to Privacy
Guitao Yang, Alexander J. Gallo, Angelo Barboni +3
This paper examines the properties of output-redundant systems, that is, systems possessing a larger number of outputs than inputs, through the lenses of the geometric approach of…
State Estimation Using a Network of Distributed Observers With Unknown Inputs
Guitao Yang, Angelo Barboni, Hamed Rezaee +1
State estimation for a class of linear time-invariant systems with distributed output measurements (distributed sensors) and unknown inputs is addressed in this paper. The objectiv…
