HOSM State Estimation and Robust PID Control of a Chemical Process
(International Federation of Automatic Control, 2016)
Gráfico de controle modificado para monitoramento de variância
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2021-09-16)
Control charts are powerful tools used by many industries to monitor the quality of their processes and detect special causes of variation. They are often used to monitor the mean of some process quality characteristic ...
Design of the statistical control of low fraction nonconforming processes restricted to small samplesPlanejamento do controle estatístico de processos com baixa fração não conforme restrito a amostras pequenas
(2007-01-01)
We present the non-conventional design of no charts used for the surveillance of processes characterized by a very low fraction nonconforming, with a costly and/or time-consuming inspection procedure. which makes the ...
Desenvolvimento de protótipos em escala reduzida para o ensino das disciplinas de controle
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2015-11-12)
This work aim to develop four reduced scale prototypes which simulate industrial processes such as: speed control, air flow control, backlight control, and position control. For that, it will be addressed the procedures, ...
Neuroevolutive Control of Industrial Processes Through Mapping Elites
(IEEE, 2021)
Classical model-based control techniques used in process control applications present a tradeoff between performance and computational load, especially when using complex nonlinear methods. Learning-based techniques that ...
Uma estratégia de integração da camada de otimização em tempo real para controle hierárquico
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-11-01)
A hierarchical control layer integration strategy is presented in this document. In particular, it is proposed to use the SSTO (Steady-State Target Optimization) layer, interfacing the RTO (Real-Time Optimization) layer ...
Recondicionamento e criação de um sistema supervisório de uma bancada didática de controle
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2014-11-26)
This paper aims at the reconditioning and creation of a supervisory system of a control didactic bench for level, flow and pressure processes for the use of students for educative ends. It also studies the definition of ...
Controle de temperatura utilizando o protocolo Foundation Fieldbus
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrônica, 2014-11-04)
This project consists of a temperature control of a thermal chamber using the Foundation Fieldbus all-digital protocol. A temperature transmitter and a Fieldbus to 4-20 mA converter were used in the project’s development. ...
Double sampling (x)over-bar control chart for a first-order autoregressive moving average process model
(Springer London Ltd, 2008-11-01)
In this paper, we consider the double sampling (DS) (X) over bar control chart for monitoring processes in which the observations can be represented as a first-order autoregressive moving average (ARMA(1, 1)) model. The ...
