Abstract Asynchronous switching between switched system and associated filter or controller frequently occurs in several applications. In this article, the fault detection problem for a class of nonlinear systems with asynchronous is addressed. To model behaviour under switching, two working modes are adopted to facilitate studies on issue. Then, based average dwell time approach, developed via solving LMIs. Furthermore, it proved that synchronous only particular case our results switching....

SUMMARY In this paper, several concepts of switching frequency are introduced to analyze the properties and performance switched systems in infinite as well finite‐time intervals. The observation is very motivating that different system performances depend on frequencies. Sufficient conditions ensuring asymptotic stability, ℓ 2 gain performance, state boundness derived basis notions frequency, respectively. Then, analysis results, control synthesis problems addressed. LMI‐based design...

The paper reports an experimental non-linear load evaluation regarding current harmonics sensitivity to supply voltage harmonics. A base for the model is proposed relying on time-domain waveform variations, rather than impedance or conductance approach. Waveform Variation Defined Model able detail provide improved correspondence actual physical operation emergence of cross-order coupling between and variations. proposal specifies implement non-impedance relation separated phase magnitude...

This paper concerns the state estimation problem for a class of uncertain non-linear Markovian jump systems, where only occurs in some ‘short’ finite-time intervals. For this boundedness error deserves our investigation. By introducing concepts stochastic stability and boundedness, sufficient conditions ensuring system's stablility are derived, then result is extended to γ -disturbance attenuation case. Based on analysis results, robust observer bounded with prescribed boundary constructed....

Current study focused on Coriandrum sativum seeds as a green low-cost biosorbent for crystal violet dye removal from wastewater.Adsorption parameters (such pH, adsorbent dosage, contact time, adsorbate concentration, and temperature), isotherm models (i.e., Langmuir, Freundlich, Dubinin-Radushkevich models), kinetic pseudo-first-order, pseudo-secondorder, intraparticle diffusion thermodynamics has been studied investigated.At optimized conditions, that is, pH 7, dose of 0.3 g, time 50 min,...

ABSTRACT The Luenberger observer technique has long been used for reliable state estimation of feedback control systems. In this paper it is employed asynchronously switched theory finite‐time stability ( FTS ) and boundedness FTB incorporated, which a relatively new concept offering open challenging problems, especially in the field robust Many real‐world systems are supposed to run fixed interval time hence design observers more significance from point view many engineering applications....

The concept of finite-time stability (FTS) has gained much attention from researchers in recent years, after the emergent utilization linear matrix inequalities (LMIs) field control systems. In this paper, FTS and boundedness (FTB) analysis synthesis procedure for a ‘finite-time H ∞ filter’ discrete-time switching systems are presented. Assuming external disturbance to be energy bounded, sufficient conditions designated filter-based system stable proposed. Considering dwell-time switching,...

SUMMARY In this note, the state estimation problem for a class of short‐time switched linear systems is investigated. By incorporating concept finite‐time stability, an observer designed to ensure error dynamics stable in switching interval under general asynchronous whereas synchronous mode its special case. A numerical example provided illustrate effectiveness our study paper. Copyright © 2013 John Wiley & Sons, Ltd.

An increase in harmonic currents the low voltage networks is progressively observed, which mainly caused due to energy-efficient modern power electronic equipment. The current harmonics, injected by this equipment, tend change waveform of distribution network. emission these loads also susceptible input waveform. Any amplitude and phase angle variation either combine or exclusively, has a visible impact on angles load's emission. This paper presents influence varying harmonic, harmonics.
