Title in Portuguese
Utilização dos modelos ARX e ARMAX em plantas industriais ruidosas
Keywords in Portuguese
ARMAX
ARX
Identificação
Sistemas industriais
Abstract in Portuguese
Técnicas experimentais de identificação de sistemas de controle têm despertado interesse na indústria devido a sua facilidade em ajustar modelos matemáticos, simplificando a formulação e a resolução de problemas de sintonia de controle de processos. Essa sintonia possibilita, também, a conservação das características de desempenho do processo industrial durante o ciclo de produção. Dessa forma, é proposto, no presente trabalho, o uso de uma técnica experimental de Identificação de Sistemas aplicados a dados coletados em ambientes industriais ruidoso, utilizando a estrutura matemática linear ARX e ARMAX. Os parâmetros dessas estruturas dessas estruturas matemática são estimados por meio do algoritmo dos Mínimos Quadrados (LS).

Abstract in English
Experimental technique for systems control identification have attracted interest in the industry due to its ease adjustment of mathematical models, simplifying the (design) and troubleshooting of line process control. (This line also makes retention performance characteristics of the manufacturing process during the production cycle possible). Thus it is proposed in this study, using an experimental technique of identification systems applied to data collected in noisy industrial ambiente, using linear mathematical structure ARX and ARMAX. These mathematical structure parameters are estimated by the algorithm of least squares (LS).
