Observation of Periodic Systems: Bridge Centralized Kalman Filtering and Consensus-Based Distributed Filtering
Jiachen Qian, Zhisheng Duan, Peihu Duan +1
Compared with linear time invariant systems, linear periodic system can describe the periodic processes arising from nature and engineering more precisely. However, the time-varyin…

Harmonic-Copuled Riccati Equations and its Applications in Distributed Filtering
Jiachen Qian, Peihu Duan, Zhisheng Duan +1
The coupled Riccati equations are cosisted of multiple Riccati-like equations with solutions coupled with each other, which can be applied to depict the properties of more complex…
