On Discrete Time Wilson Systems [PDF]
Journal of Mathematics, 2020 In this paper, we define the discrete time Wilson frame (DTW frame) forl2ℤand discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames. Furthermore, a necessary and a sufficient condition for the DTW frame in terms of Zak transform are given.

Frontiers in Energy Research, 2022 This study proposes a polymorphic cooperative control system for microgrid consisting of a service layer, a control layer, a data layer, and a power layer to apply a resilient-distributed secondary control strategy to distributed generators (DGs) from ...

Design of a Discrete-time Sliding Mode Controller for Nonlinear Affine Systems based on Disturbance Estimation [PDF]
Journal of Electrical and Computer Engineering Innovations, 2017 Background and Objectives: Nowadays, because of accuracy, speed, cost, and flexibility of digital control laws, control systems are implemented by computers, microprocessors or DSP chips.

Discrete-time randomized sampling [PDF]
ICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2002 This paper explores the use of randomized sampling in implementing convolution in discrete-time with application to the areas of approximate filtering, low-power filter design, and hardware failure modeling. Three distinct randomized sampling methods are presented and additive error models as well as second-order error statistics are derived for these ...

Bubbles in discrete-time models
Finance and Stochastics, 2022 AbstractWe introduce a new definition of bubbles in discrete-time models based on the discounted stock price losing mass under an equivalent martingale measure at some finite drawdown. We provide equivalent probabilistic characterisations of this definition and give examples of discrete-time martingales that are bubbles and others that are not.

Characterizing sustainability in discrete time [PDF]
Economic Theory, 2018 AbstractWe examine the investment rule that must be satisfied by an efficient and egalitarian path in a discrete-time version of the Dasgupta–Heal–Solow model of capital accumulation and resource depletion. In the discrete-time model, competitive valuation of net investments in terms of early and late pricing differs.

Nonlinear Decoupling in Discrete Time
IFAC Proceedings Volumes, 1989 Abstract In this paper we study static and dynamic single-input-single-output decoupling for the class of discrete-time nonlinear systems. We give necessary and sufficient conditions which ensure the static decoupling and the "state free "left invertibility of each input-output channel.
