Resumo: | Due to the increased availability of low cost network technology, the use of networks to interconnect sensors, actuators and controllers is becoming widely accepted for the implementation of feedback control systems. Such type of feedback implementation, wherein the control loops are closed through a real-time network, are called Network Controlled Systems (NCS). When implementing a NCS, the underlying communication network must provide a timely communication service, which must be the adequate to fulfil the control application requirements. Therefore, the assessment of the network responsiveness to the real-time requirements of the control application is a fundamental issue. Both PROFIBUS and CAN networks are usually considered suitable to support small-scale NCS, due to their real-time capabilities. However, their temporal responsiveness is highly dependent on both the timing characteristics of the supported message streams, such as its periodicity and the related message lengths. In this paper, we compare the timing properties of both CAN and PROFIBUS control networks. Basically, we assess their capability to support Network Controlled Systems, through the evaluation of the related worst-case message’s response time. A small example of a NCS is then used to assess the capability of the CAN control network to fulfil control application requirements. |

Tal tipo de implementação, na qual as malhas de controle são fechadas utilizando uma rede de comunicação de tempo real, são chamadas de Sistemas de Controle via Redes (ou NCS, para Networked Control Systems). Quando implementamos um NCS, a rede de comunicação subjacente deve fornecer um serviço de comunicação de tempo-real que satisfaça os requisitos das aplicações de controle. Em conseqüência, é fundamental a avaliação da correção do tempo de resposta da rede de comunicação, quando comparado com os requisitos da aplicação de controle. As redes CAN e PROFIBUS são habitualmente consideradas aceitáveis para suportar NCS de pequena escala, devido a sua capacidade de comunicação de tempo real. No entanto, é também conhecido que a sua correção temporal é altamente dependente das características dos fluxos de mensagens suportados, tais como a sua periodicidade e o comprimento de mensagens relacionado. Neste artigo, comparamos as propriedades temporais das redes de controle CAN e PROFIBUS. Basicamente, avaliamos a sua capacidade para suportar sistemas controlados por computador, através do cálculo do tempo de resposta das mensagens no pior caso. Um pequeno exemplo de um NCS é utilizado para comparar a capacidade dessas redes de controle para satisfazer os requisitos da aplicação de controle suportada.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/221010.4025/actascitechnol.v25i2.2210Acta Scientiarum.

Due to the increased availability of low cost network technology, the use of networks to interconnect sensors, actuators and controllers is becoming widely accepted for the implementation of feedback control systems. Such type of feedback implementation, wherein the control loops are closed through a real-time network, are called Network Controlled Systems (NCS). When implementing a NCS, the underlying communication network must provide a timely communication service, which must be the adequate to fulfil the control application requirements. Therefore, the assessment of the network responsiveness to the real-time requirements of the control application is a fundamental issue. Both PROFIBUS and CAN networks are usually considered suitable to support small-scale NCS, due to their real-time capabilities. However, their temporal responsiveness is highly dependent on both the timing characteristics of the supported message streams, such as its periodicity and the related message lengths. In this paper, we compare the timing properties of both CAN and PROFIBUS control networks. Basically, we assess their capability to support Network Controlled Systems, through the evaluation of the related worst-case message’s response time. A small example of a NCS is then used to assess the capability of the CAN control network to fulfil control application requirements. |
