 Abstract— L'identification des systèmes est utilisée pour construire modèles

 Abstract— L'identification des systèmes est utilisée pour construire modèles mathématiques d'un système dynamique basé sur données mesurées. .Pour concevoir les meilleurs contrôleurs linéaire ou systèmes non linéaires, la modélisation mathématique est le principal défi. Pour résoudre ce défi conventionnel et l'identification intelligente est recommandée. Système d'identification est divisée en différents algorithmes .Dans ce recherche, quatre types importants d’algorithmes sont comparés à identifier les systèmes hautement non linéaires, à savoir : AutoRegressive with eXternal model input (ARX) , et Auto Regressive moving Average with eXternal model input (Armax) , Output-Error (OE)et finalement Box-Jenkins(BJ) I. INTRODUCTION Le but de L’utilisation de la référence ou le modèle de benchmark est de comparer les différentes méthodes d’identification des processus où chaque système est considéré comme une boite noire (sans considérer son fonctionnement interne), afin de modéliser les systèmes Non linéaires. L’objectif de l'indice de référence est de ne Pas installer une concurrence. Il est bien connu qu'il est toujours possible de créer les conditions expérimentales favorite afin d’obtenir des approche de modélisation Similaire au comportement du système à modélisé. Le but est d'obtenir une meilleure compréhension sur les capacités de différentes méthodes de modélisation et d'identification Le but de cette étude est de comparer deux approches de modélisation des systèmes OE t ARX en variant l’ordre du système de 0 à 10.

The authors of the accepted manuscripts will be given a copyright form and the form should accompany your final submission. I. MATH If you are using Word, use either the Microsoft Equation Editor or the MathType add-on (http://www.mathtype.com) for equations in your paper (Insert | Object | Create New | Microsoft Equation or MathType Equation). “Float over text” should not be selected. II. UNITS Use either SI (MKS) or CGS as primary units. (SI units are strongly encouraged.) English units may be used as secondary units (in parentheses). This applies to papers in data storage. For example, write “15 Gb/cm2 (100 Gb/in2).” An exception is when English units are used as identifiers in trade, such as “3½ in disk drive.” Avoid combining SI and CGS units, such as current in amperes and magnetic field in oersteds. This often leads to confusion because equations do not balance dimensionally. If you must use mixed units, clearly state the units for each quantity in an equation. The SI unit for magnetic field strength H is A/m. However, if you wish to use units of T, either refer to magnetic flux density B or magnetic field strength symbolized as µ0H. Use the center dot to separate compound units, e.g., “A·m2.” III. HELPFUL HINTS A. Figures and Tables Because the final formatting of your paper is limited in scale, you need to position figures and tables at the top and bottom of each column. Large figures and tables may span both columns. Place figure captions below the figures; place table titles above the tables. If your figure has two parts, include the labels “(a)” and “(b)” as part of the artwork. Please verify that the figures and tables you mention in the text actually exist. Do not put borders around the outside of your figures. Use the abbreviation “Fig.” even at the beginning of a sentence. Do not abbreviate “Table.” Tables are numbered with Roman numerals. Include a note with your final paper indicating that you request color printing. Do not use color unless it is necessary for the proper interpretation of your figures. Figure axis labels are often a source of confusion. Use words rather than symbols. As an example, write the quantity “Magnetization,” or “Magnetization M,” not just “M.” Put units in parentheses. Do not label axes only with units. As in Fig. 1, for example, write “Magnetization (A/m)” or “Magnetization (A m1),” not just “A/m.” Do not label axes with a ratio of quantities and units. For example, write “Temperature (K),” not “Temperature/K.” Multipliers can be especially confusing. Write “Magnetization (kA/m)” or “Magnetization (103 A/m).” Do not write “Magnetization (A/m)  1000” because the reader would not know whether the top axis label in Fig. 1 meant 16000 A/m or 0.016 A/m. Figure labels should be legible, approximately 8 to 12 point type. TABLE I: THE ARRANGEMENT OF CHANNELS Channels Group 1 Group 2 … Group c Main channel Channel 1 Channel 2 … Channel c Assistant channel Channel 2 Channel 3 … Channel 1 Fig. 1. Magnetization as a function of applied field. B. References Number citations consecutively in square brackets [1]. The sentence punctuation follows the brackets [2]. Multiple references [2], [3] are each numbered with separate brackets [1]–[3]. When citing a section in a book, please give the relevant page numbers [2]. In sentences, refer simply to the reference number, as in [3]. Do not use “Ref. [3]” or “reference [3]” except at the beginning of a sentence: “Reference [3] shows ... .” Number footnotes separately in superscripts (Insert | Footnote).1 Place the actual footnote at the bottom of the column in which it is cited; do not put footnotes in the reference list (endnotes). Use letters for table footnotes (see Table I). Please note that the references at the end of this document are in the preferred referencing style. Give all authors’ names; do not use “et al.” unless there are six authors or more. Use a space after authors' initials. Papers that have not been published should be cited as “unpublished” [4]. Papers that have been submitted for publication should be cited as “submitted for publication” [5]. Papers that have been accepted for publication, but not yet specified for an issue should be cited as “to be published” [6]. Please give affiliations and addresses for private communications [7]. Capitalize only the first word in a paper title, except for proper nouns and element symbols. For papers published in translation journals, please give the English citation first, followed by the original foreign-language citation [8]. 1It is recommended that footnotes be avoided (except for the unnumbered footnote with the receipt date on the first page). Instead, try to integrate the footnote information into the text. C. Abbreviations and Acronyms Define abbreviations and acronyms the first time they are used in the text, even after they have already been defined in the abstract. Abbreviations such as SI, ac, and dc do not have to be defined. Abbreviations that incorporate periods should not have spaces: write “C.N.R.S.,” not “C. N. R. S.” Do not use abbreviations in the title unless they are unavoidable (for example, “INTERNATIONAL JOURNAL OF TRADE, ECONOMICS AND FINANCE” in the title of this article). D. Equations Number equations consecutively with equation numbers in parentheses flush with the right margin, as in (1). First use the equation editor to create the equation. Then select the “Equation” markup style. Press the tab key and write the equation number in parentheses. To make your equations more compact, you may use the solidus ( / ), the exp function, or appropriate exponents. Use parentheses to avoid ambiguities in denominators. Punctuate equations when they are part of a sentence, as in . ) ( ) ( ) | | ( exp )] 2 ( / [ ) , ( 0 2 1 1 0 0 2 0 2          d r J r J z z r d dr r F i i j r         (1) Be sure that the symbols in your equation have been defined before the equation appears or immediately following. Italicize symbols (T might refer to temperature, but T is the unit tesla). Refer to “(1),” not “Eq. (1)” or “equation (1),” except at the beginning of a sentence: “Equation (1) is ... .” E. Other Recommendations Use one space after periods and colons. Hyphenate complex modifiers: “zero-field-cooled magnetization.” Avoid dangling participles, such as, “Using (1), the potential was calculated.” [It is not clear who or what uploads/s3/ ijtef-template2.pdf
