Stability of Phase-modulated Quantum Key Distribution System
, 2004 Phase drift and random fluctuation of interference visibility in double unbalanced M-Z QKD system are observed and distinguished. It has been found that the interference visibilities are influenced deeply by the disturbance of transmission fiber.

Stability of multiquark systems [PDF]
AIP Conference Proceedings, 2000 We give a brief review of developments in the field of exotic hadrons formed of more than three quarks and/or antiquarks. In particular we discuss the stability of multiquark systems containing heavy flavours. We show that the gluon exchange model and the chiral constituent quark model based on Goldstone boson (pseudoscalar meson) exchange give ...

Phase-Locked Loop Research of Grid-Connected Inverter Based on Impedance Analysis
Energies, 2018 In order to improve the phenomenon that a traditional phase-locked loop based on a double second-order generalized integrator (DSOGI-PLL) cannot track signal amplitude and phase accurately when the input signal contains DC components and high-order ...

The Stability and Stabilization of Stochastic Delay‐Time Systems [PDF]
Mathematical Problems in Engineering, 2014 The aim of this paper is to investigate the stability and the stabilizability of stochastic time‐delay deference system. To do this, we use mainly two methods to give a list of the necessary and sufficient conditions for the stability and stabilizability of the stochastic time‐delay deference system.

Existence and Stability of nT-Periodic Orbits in the Boost Converter
Applied Sciences, 2022 In high load conditions, the boost converter presents some phenomena, such as chattering, chaos, subharmonics, and nT-periodic orbits, which require studying them with the aim of reducing the effects and improving the performance of these electronic ...

New heuristic-based design of robust power system stabilizers
, 2004 This paper proposes a new robust design of power system stabilizers (PSSs) in a multimachine power system using a heuristic optimization method. The structure of each PSS used is similar to that of a conventional lead/lag stabilizer.

Stability Analysis and Stabilization of Systems With Input Backlash [PDF]
IEEE Transactions on Automatic Control, 2014 This technical note deals with the stability analysis and stabilization of linear systems with backlash in the input. Uniform ultimate boundedness stability and stabilization problems are tackled allowing to characterize suitable regions of the state space in which the closed-loop trajectories can be captured.

Stabilization of Hamiltonian systems [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 1986 Stabilization of Hamiltonian control systems is considered, using the first and the second Lypunov method. As the main result sufficient conditions are stated for an analytic Hamiltonian control system to be made locally asymptotically stable by an extended output feedback i.e. both the outputs and their derivatives are fed back.

Design and Modeling of Oceanographic Environment Adaptive Variable Pumps
IEEE Access, 2020 Variable pumps are important hydraulic power units in deep-sea exploitation due to their good energy-saving and high precision capabilities. However, their application in such hostile environment suffers from the risk of control failure.
