Journal ArticleDOI
Consensus of Quantum Networks With Directed Interactions: Fixed and Switching Structures
TL;DR: It is shown that the network state always converges along the equation, and the convergence limit is determined by the generating subgroup of the permutation operators, and a tight graphical criterion regarding when such limit admits a reduced-state consensus is given.
Journal ArticleDOI
Two-step feedback preparation of entanglement for qubit systems with time delay
Yanan Liu,Yanan Liu,Daoyi Dong,Sen Kuang,Ian R. Petersen,Hidehiro Yonezawa,Hidehiro Yonezawa +6 more
TL;DR: In this article, two control strategies based on the Lyapunov method were designed to prepare a class of entangled states for qubit systems with a constant delay time, and the stability of these two strategies was proved.
Proceedings Article
Improved control of atomic force microscope for high-speed image scanning
TL;DR: In this paper, an observer based model predictive control (OMPC) scheme for accurate tracking and fast scanning of an atomic force microscope (AFM) is presented, which is based on an identified model of the AFM piezoelectric tube (PZT) scanner.
Proceedings ArticleDOI
Nonlinearity compensation for improved nanopositioning of atomic force microscope
TL;DR: An observer-based model predictive control scheme with a notch filter which aims to compensate for the effects of creep, hysteresis, cross-coupling, and vibration in piezoactuators in order to improve the nanopositioning of an atomic force microscope (AFM).
Proceedings ArticleDOI
Cross-coupling Effect Compensation of an AFM Piezoelectric Tube Scanner for Improved Nanopositioning
TL;DR: The design of this controller is based on an identified MIMO model of the AFM PTS, and a damping compensator is designed and included in the feedback loop with the plant to suppress the vibration of the PTS at the resonant frequency.
