Abstract: In this brief, a dynamic system emulator for the Planar Vertical Take Off and Landingaircraft (PVTOL) based-on analog circuits is presented. It is designed in VerilogA. The structureof the emulator is simple and easy to implement. To the best of the authors knowledge, this isthe rst time that a dynamic system emulator is implemented for the PVTOL system.

1. INTRODUCTION

In the last years, Unmanned Aerial Vehicles (UAVs) havereceived growing interest in industrial and academic re-

search. They may prove useful for many civilian missionssuch as video supervision of road traffic, surveillance of urban districts, forest re detection or building inspec-tion. This progress was motivated by the enormous mil-itary/civil applications of such vehicles accompanied withthe technological progress in sensors, actuators, processorsand power storage devices.The Planar Vertical Take Off and Landing aircraft (PV-TOL) represents a challenging nonlinear system problemthat is often considered a benchmark model in aerospaceengineering to design control laws for Unmanned AerialVehicles (UAVs) since it can be seen as the projection of a six degree of freedom ying body into a vertical planeattached to the body ? .

2. PROCEDURE FOR PAPER SUBMISSION

Next we see a few subsections.

2.1 Review Stage

For submission guidelines, follow instructions on papersubmission system as well as the event website.

Note that conferences impose strict page limits, so it willbe better for you to prepare your initial submission in the

Sponsor and nancial support acknowledgment goes here. Papertitles should be written in uppercase and lowercase letters, not alluppercase.

camera ready layout so that you will have a good estimatefor the paper length. Additionally, the effort required fornal submission will be minimal.

2.2 Equations Some words might be appropriate describing equation (1),if we had but time and space enough.

F t

= D 2 F x 2

. (1)

See ? , ? , ? and ? .

Example. This equation goes far beyond the celebratedtheorem ascribed to the great Pythagoras by his followers.Theorem 1. The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengthsof the other two sides.

Proof. The square of the length of the hypotenuse of aright triangle equals the sum of the squares of the lengthsof the other two sides.

Of course LaTeX manages equations through built-inmacros. You may wish to use the amstex package forenhanced math capabilities.

2.3 Figures

To insert gures, use the graphicx package. Althoughother graphics packages can also be used, graphicx issimpler to use. See Fig. 1 for an example.

Figures must be centered, and have a caption at thebottom.

2.4 Tables

Tables must be centered and have a caption above them,numbered with Arabic numerals. See table 1 for an exam-ple.

2.5 Final Stage

Authors are expected to mind the margins diligently.Papers need to be stamped with event data and paginatedfor inclusion in the proceedings. If your manuscript bleedsinto margins, you will be required to resubmit and delaythe proceedings preparation in the process.

Page margins. See table 1 for the page margins speci-cation. All dimensions are in centimeters .

2.6 PDF Creation

All fonts must be embedded/subsetted in the PDF le.

Use one of the following tools to produce a good qualityPDF le:

PDFLaTeX is a special version of LaTeX by Han TheThanh which produces PDF output directly using Type-1fonts instead of the standard dvi le. It accepts guresin JPEG, PNG, and PDF formats, but not PostScript.Encapsulated PostScript gures can be converted to PDFwith the epstopdf tool or with Adobe Acrobat Distiller.

Generating PDF from PostScript is the classical way of producing PDF les from LaTeX. The steps are:

(1) Produce a dvi le by running latex twice.

(2) Produce a PostScript ( ps ) le with dvips .(3) Produce a PDF le with ps2pdf or Adobe AcrobatDistiller.

2.7 Copyright Form

IFAC will put in place an electronic copyright transfersystem in due course. Please do not send copyright formsby mail or fax. More information on this will be madeavailable on IFAC website.

3. UNITS

Use SI as primary units. Other units may be used assecondary units (in parentheses). This applies to pa-pers in data storage. For example, write 15 Gb / cm2

(100 Gb / in2 ). An exception is when English units areused as identiers in trade, such as 3.5 in disk drive.Avoid combining SI and other units, such as current inamperes and magnetic eld in oersteds. This often leads toconfusion because equations do not balance dimensionally.If you must use mixed units, clearly state the units foreach quantity in an equation. The SI unit for magneticeld strength H is A/ m. However, if you wish to use unitsof T, either refer to magnetic ux density B or magneticeld strength symbolized as 0 H . Use the center dot toseparate compound units, e.g., A m2 .

4. HELPFUL HINTS

4.1 Figures and Tables

Figure axis labels are often a source of confusion. Usewords rather than symbols. As an example, write thequantity Magnetization, or Magnetization M, not justM. Put units in parentheses. Do not label axes onlywith units. For example, write Magnetization (A / m) or

Magnetization (Am 1

), not just A / m. Do not labelaxes with a ratio of quantities and units. For example,write Temperature (K), not Temperature / K.

Multipliers can be especially confusing. Write Magne-tization (kA / m) or Magnetization (10 3 A/ m). Do notwrite Magnetization (A / m) 1000 because the readerwould not know whether the axis label means 16000A / mor 0.016A/ m.

4.2 References

Use Harvard style references (see at the end of thisdocument). With L ATEX, you can process an externalbibliography database using bibtex ,

1

or insert it directlyinto the reference section. Footnotes should be avoided asfar as possible. Please note that the references at the endof this document are in the preferred referencing style.Papers that have not been published should be cited asunpublished. Capitalize only the rst word in a papertitle, except for proper nouns and element symbols.

4.3 Abbreviations and Acronyms

Dene abbreviations and acronyms the rst time they areused in the text, even after they have already been denedin the abstract. Abbreviations such as IFAC, SI, ac, and dc

do not have to be dened. Abbreviations that incorporate1 In this case you will also need the ifacconf.bst le, which is partof the ifaconf package.


3/3

periods should not have spaces: write C.N.R.S., not C.N. R. S. Do not use abbreviations in the title unless theyare unavoidable (for example, IFAC in the title of thisarticle).

4.4 Equations

Number equations consecutively with equation numbersin parentheses ush with the right margin, as in (1). Tomake your equations more compact, you may use thesolidus ( / ), the exp function, or appropriate exponents.Use parentheses to avoid ambiguities in denominators.Punctuate equations when they are part of a sentence,as in

r 2

0

F (r, )drd = [r 2 / (20 )]

inf

0

exp( |zj zi |) 1 J 1 (r 2 )J 0 (r i )d

(2)

Be sure that the symbols in your equation have beendened before the equation appears or immediately fol-lowing. 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 . . . .

4.5 Other Recommendations

Use one space after periods and colons. Hyphenate com-plex modiers: zero-eld-cooled magnetization. Avoiddangling participles, such as, Using (1), the potential wascalculated (it is not clear who or what used (1)). Writeinstead: The potential was calculated by using (1), orUsing (1), we calculated the potential.

A parenthetical statement at the end of a sentence ispunctuated outside of the closing parenthesis (like this).(A parenthetical sentence is punctuated within the paren-theses.) Avoid contractions; for example, write do notinstead of don t. The serial comma is preferred: A, B,and C instead of A, B and C.

5. CONCLUSION

A conclusion section is not required. Although a conclusionmay review the main points of the paper, do not replicatethe abstract as the conclusion. A conclusion might elabo-rate on the importance of the work or suggest applicationsand extensions.
