Resumo: This article seeks to find the tuning for a driver for the product specification of the top of a distillation column, in order to keep the product always in the desired specification  range and can generate great savings for the process. He carried out the approach system in a first order transfer function with the aid of the simulator ControlStation 3.5 and Excel. After we met the open loop parameters such as Kp (process gain), T (time constant) minutes and ? (delay constant). Subsequently, he selected the PID controller as it is indicated to slow processes and / or who do not wish residual errors and many swings. It analyzed three cases: The variation of the disturbance variable, the variation of the set value (SP) and the start of the process. For all of them the driver parameters were determined by Ziegler and Nichols tuning method in open loop, getting a Kc (controller gain) value of 3,957, a Ti (integration time) of 16 minutes and Td (time derivation) of 4 minutes. It was noted then that in both cases, the valuesfound in this line met all the pre-established criteria. Finally, we compared the results obtained by Ziegler and Nichols tuning with the other tuning methods, which further evidenced its efficiency.

Realizou-se a aproximação do sistema em uma função de transferência de primeira ordem, com o auxílio do simulador ControlStation 3.5 e do Excel. Após, encontrou-se os parâmetros de malha aberta como Kp (ganho do processo), t (constante de tempo) minutos e ? (constante de atraso). Posteriormente, selecionou-se o controlador do tipo PID já que ele é indicado para processos lentos e/ou que não desejam erros residuais e muitas oscilações. Analisou-se três casos: A variação da variável distúrbio, a variação do valor definido (SP) e a partida do processo. Para todos eles os parâmetros do controlador foram determinados pelo método de sintonia de Ziegler e Nichols em malha aberta, obtendo um Kc (ganho do controlador) com valor de 3,957, um Ti (tempo de integração) de 16 minutos e um Td (tempo de derivação) de 4 minutos. Notou-se então que para ambos os casos, os valores encontrados por esta sintonia satisfez todos os critérios pré-estabelecidos. Por fim, comparou-se os resultados obtidos pela sintonia de Ziegler e Nichols com os de outros métodos de sintonia, o que evidenciou ainda mais a sua eficiência. Universidade Federal de Viçosa - UFV2016-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/kswpshttps://periodicos.ufv.br/jcec/article/view/244694160202301604710.18540/jcecvl2iss3pp047-060The Journal of Engineering and Exact Sciences; Vol. 2 No. 3 (2016); 047-060The Journal of Engineering and Exact Sciences; Vol. 2 Núm. 3 (2016); 047-060The Journal of Engineering and Exact Sciences; v. 2 n. 3 (2016); 047-0602527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941602023016047/pdfBraga, Eduardo Ramosinfo:eu-repo/semantics/openAccess2020-07-14T22:45:34Zoai:ojs.periodicos.ufv.br:article/2171Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2020-07-14T22:45:34Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
