Stability of uncertain systems with time-varying delays

open access: yesFifth World Congress on Intelligent Control and Automation (IEEE Cat. No.04EX788), 2004
This paper provides a new criterion for robust asymptotical stability of a class of uncertain systems with multiple time-varying delays and nonlinear uncertainties based on LaSalle theorem. Firstly, we gave a contractive invariant set for time-delay systems, and then we derived the condition in which the system would be attracted into this invariant ...

Asynchronous Delayed Optimization With Time-Varying Minibatches

IEEE Journal on Selected Areas in Information Theory, 2021
Large-scale learning and optimization problems are often solved in parallel. In a master-worker distributed setup, worker nodes are most often assigned fixed-sized minibatches of data points to process. However, workers may take different amounts of time to complete their per-batch calculations.

Optimal estimation of time-varying delay

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
The authors report on time-varying delay estimation in a multisource single direct acoustic path environment. The signals are stochastic nonstationary processes. The time delays are deterministic time-varying functions described by a finite dimensional vector theta of unknown parameters. The observation noise is spatially correlated.

On time‐varying cyclic delay diversity

European Transactions on Telecommunications, 2006
AbstractCyclic delay diversity (CDD) was introduced in 2001 to obtain spatial diversity in an orthogonal frequency division multiplexing (OFDM) based transmission system. In contrast to space‐time codes, CDD introduces no additional effort at the receiver side, since CDD changes only the channel impulse response seen by the receiver by increasing the ...
