Discrete-time current regulator for AC machine drives by Yuan, Xin, Chen, Jiahao, Jiang, Chaoqiang, Lee, Christopher Ho Tin

“…In a practical alternating current (AC) machine drive system, a direct discrete-time current regulator model based on a zero order hold (ZOH) equivalent discrete-time machine model should be the first choice to be established compared with the discrete-time current regulator model based on continuous-time machine model when designing a digital current regulator. …”

Global stability of discrete-time competitive population models by Baigent, Stephen, Hou, Zhanyuan

“…We develop practical tests for the global asymptotic stability of interior fixed points for discrete-time competitive population models. Our method constitutes the extension to maps of the Split Lyapunov method developed for differential equations. …”

Exponential Stabilizaiton of Discrete−time Switched Linear Systems by Zhang, W, Abate, A, Hu, J, Vitus, M

DISCRETE-TIME MULTIVARIABLE CRITERION FOR LIMIT-CYCLE PREDICTIONS by Kouvaritakis, B, Cameron, R

“…Circulant matrices and their properties provide a new interpretation of limit-cycle phenomena in discrete-time nonlinear feedback systems. The present work extends the results of a recent paper in order to derive a multivariable circle type of criterion with a suitable Nyquist interpretation.…”

O-minimal invariants for discrete-time dynamical systems by Almagor, S, Chistikov, D, Ouaknine, J, Worrell, J

“…Already for the simplest variants of linear loops the question of termination relates to deep open problems in number theory, such as the decidability of the Skolem and Positivity Problems for linear recurrence sequences, or equivalently reachability questions for discrete-time linear dynamical systems. In this article, we introduce the class of o-minimal invariants, which is broader than any previously considered, and study the decidability of the existence and algorithmic synthesis of such invariants as certificates of non-termination for linear loops equipped with a large class of halting conditions. …”

Observation of a Prethermal U(1) Discrete Time Crystal by Andrew Stasiuk, Paola Cappellaro

“…A time crystal is a state of periodically driven matter that breaks discrete time-translation symmetry. Time crystals have been demonstrated experimentally in various programmable quantum simulators, and they exemplify how nonequilibrium, driven quantum systems can exhibit intriguing and robust properties absent in systems at equilibrium. …”
