A modelagem e simulac'ao desse tipo de sistemas e uma tarefa complicada e propicia a erros. Por isso um metodo meticuloso e necessario para tal tarefa. Automato Hibrido Linear - do ingles Linear Hybrid Automata (LHA) - e um modelo que combina elementos discretos, tipicamente chamado automato de estado finito, com variaveis continuas definidas por suas equac'oes diferenciais. Neste trabalho, usamos tecnicas baseadas em logica de reescrita em conjunto com modelagem atraves de LHA para simular a operac'ao de um CPS. Dessa maneira exploramos metodos formais na simulac'ao de um CPS. No metodo proposto o sistema completo que representa o CPS emerge do produto sincrono das partes que compoem o sistema. Dessa maneira, o pro- cesso de especificac'ao do CPS e simplificado tremendamente. Com a tecnica apresentada e justificada, dois exemplos praticos sao apresentados - o sistema deа2-reservatorios e o Aquecedor de agua - e modelados usando a metodologia proposta. O processo e iniciado com os LHAs dos componentes dos sistemas, que sao entao implementados em Maude - uma ferramenta de logica de reescrita. Na sequencia o produto sincrono e utilizado para compor os sistemas e permitir sua simulac'ao.

The modeling and simulation of such systems is a hard task and error-prone that require meticulous techniques. Linear Hybrid Automata (LHA) is a model that combines discrete elements, usually called finite state automata, with continuous variables described by differential equations. This work uses a rewriting logic-based technique alongside LHA modeling techniques to simulate CPS execution, thus exploring the use of formal methods. In the proposed method the final system emerges as the synchronous product of its constituent components, thus simplifying the whole specification process. Then two case studies - the 2-reservoir problem and the Water-Heater problem - are modeled using the proposed method. We start from system components modified Linear Hybrid Automata and implement the full system in Maude, a rewriting logic tool. Then compose the full systems through the synchronous product of their composing elements. Last, but not least, we simulate the operation of both CPS. 61РhP:p▀nj░В. ░╞A!░е"░е#РЙ$РЙ%░░─░─ Р─ЖЬШЮЮЮЮЮЮЮЮ666666666vvvvvvvvv666666>666666666666666666666666666и6666666666╕666666666666hH66666666666666666666666666666666666666666666666666666666666666666░6@@ё @ NormalCJ_HaJmHsHtH>AЄ б> 0Fonte parсg. padrуoTiє │T 0 Tabela normalЎ4╓ l4╓aЎ ,kЇ ┴, 0 Sem lista B^@ЄB Сw;0 Normal (Web)дdдd[$\$Q $    оп╣║O P S Ш0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААS KИ0ЇZв" в" в" -;<CZ`ЗТвий▒╫█ NWS Zg▌√nw¤ ┐╔╫█╫┌·■S 33п║S S  ╠cIm═cIm╠cIm╬cIm╤cIm╧cIm╨cIm╨cIm╤cIm╒cIm╥cIm╨cIm╙cIm╨cIm╘cIm╠cIm╒cIm═cImхLСw;▀njrП∙LП>╖S  @А┌┌PX╘НН┌┌@Q @@ @@@  Unknown            GР :рAx└  Times New Roman5РАSymbol3&Р  :рCx└  ArialYР SFRM1200Times New RomanSРCMR12Times New Roman"AИЁ─йЕ3h'╪kvЗЬ╡Ь╡!ЁеЙ┤┤ББ24L L Ё№ (Ё $P                     Сw;2  hTitulo:A Rewriting Logic approach for the specification and validation of Modular Cyber Physical SystemsHelioHelio■ рЕЯЄ∙OhлС+'│┘0╨РШ (4@P `l М Ш д░╕└╚фlTitulo:A Rewriting Logic approach for the specification and validation of Modular Cyber Physical SystemsHelioNormalHelio2Microsoft Office Word@F├#@ЖЎЫз-╘@`▒+"╒Ь╡■ ╒═╒Ь.УЧ+,∙о0P hp|ДМФ Ьдм┤ ╝ 1фL ц iTitulo:A Rewriting Logic approach for the specification and validation of Modular Cyber Physical Systems Tэtulo ■   ■    !"■   $%&'()*■   ¤   -■   ■   ■                                                                                                                                                                                                                                                                                                                                   Root Entry         └FА╩╞I"╒/А1Table        WordDocument        8$SummaryInformation(    DocumentSummaryInformation8            #CompObj            u                        ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■       └F#Documento do Microsoft Office Word MSWordDocWord.Document.8Ї9▓q
