A continuous time model for observer-based frequency tracking
Results in Control and Optimization, 2023 Frequency tracking has been the focus of several research works for decades. One common method is to utilize a state observer to dynamically estimate the frequency of the measured signal.

Synchronization control of fractional order linear systems based on state estimation
Nantong Daxue xuebao. Ziran kexue ban, 2023 This study focuses on the synchronization control of a class of fractional-order linear systems with orders between(1, 2), based on state observers. State observers and feedback controllers are designed to estimate the unknown states of the response ...

Correlations in the EPR States Observables
Entropy, 2023 The identification and physical interpretation of quantum correlations, more recently explored beyond entanglement, is not always a simple task. Two assumptions that, at least in principle, should lead to a relatively large dispersion for the observables of a quantum bipartite formed by systems I and II are to assume that; (a) all the possible ...
