Boundedness control sets for linear systems on Lie groups

open access: yesOpen Mathematics, 2018
Let Σ be a linear system on a connected Lie group G and assume that the reachable set 𝓐 from the identity element e ∈ G is open. In this paper, we give an algebraic condition to warrant the boundedness of the existent control set with a nonempty interior

Linear Filters and Non-Linear Systems

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1992
SUMMARY It has been asserted in the literature that the low pass filtering of time series data may lead to erroneous results when calculating attractor dimensions. Here we prove that finite order, non-recursive filters do not have this effect. In fact, a generic, finite order, non-recursive filter leaves invariant all the quantities that

Electrostatic Discharge Current Linear Approach and Circuit Design Method

open access: yesEnergies, 2010
The Electrostatic Discharge phenomenon is a great threat to all electronic devices and ICs. An electric charge passing rapidly from a charged body to another can seriously harm the last one.

Linear system identification via atomic norm regularization [PDF]

open access: yesIEEE Conference on Decision and Control, 2012
This paper proposes a new algorithm for linear system identification from noisy measurements. The proposed algorithm balances a data fidelity term with a norm induced by the set of single pole filters.

Higher-Order State and Disturbance Observer With $O(T^{3})$ Errors for Linear Systems

open access: yesIEEE Access, 2019
In this paper, a new observer, named as the higher-order observer, is proposed for simultaneously estimating the system state and disturbance. When the usual assumptions on the disturbance are satisfied, the magnitudes of the state and disturbance ...

Novel stability criterion for linear system with two additive time-varying delays using general integral inequalities

open access: yesAIMS Mathematics, 2021
The stability analysis strategy for continuous linear system with two additive time-varying delays is proposed in this paper. First, for the purpose of analysis, the novel Lyapunov-Krasovskii functional (LKF) consisting of integral terms based on the ...
