Relations Between Generalized JST Algorithm and Kalman Filtering Algorithm for Time Scale Generation
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this paper, we present a generalized Japan Standard Time algorithm (JST-algo) for higher-order atomic clock ensembles and mathematically clarify the relations of the (generalize…
Structured Kalman Filter for Time Scale Generation in Atomic Clock Ensembles
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this article, we present a structured Kalman filter associated with the transformation matrix for observable Kalman canonical decomposition from conventional Kalman filter (CKF)…
Higher-Order Allan Variance for Atomic Clocks of Arbitrary Order: Mathematical Foundation
Takayuki Ishizaki, Taichi Ichimura, Takahiro Kawaguchi +2
In this paper, we perform a time-domain analysis of the higher-order Allan variance for atomic clock models of arbitrary order. Adopting a standard atomic clock model where the tim…
Modularity-in-Design of Dynamical Network Systems: Retrofit Control Approach
Takayuki Ishizaki, Hampei Sasahara, Masaki Inoue +2
In this paper, we develop a modular design method of decentralized controllers for linear dynamical network systems, where multiple subcontroller designers aim at individually regu…
Retrofit Control with Approximate Environment Modeling
Takayuki Ishizaki, Takahiro Kawaguchi, Hampei Sasahara +1
In this paper, we develop a retrofit control method with approximate environment modeling. Retrofit control is a modular control approach for a general stable network system whose…
