The prediction, quantification and evaluation of advanced process control benefits

Bawden, Neil Martin 15 July 2016 (has links)
A project report submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg in partial fulfillment of the requirements for the degree of Master of Science in Engineering. Johannesburg 1992 / It has been suggested that the inability to quantify the financial benefits of advanced process control is a. key barrier to hs more widespread use and acceptance. This report discusses the financial analysis of advanced process control opportunities. Potential benefits of advanced control are predicted by considering the power spectral density of load disturbances likely to affect the control system, and the ideal characteristlcs of feedback systems as proposed by H.W. Bode. Financial ratio analysis and modem measures of profitabilty, such as Discounted Cash Flow Rate of Return (DCFRR) and Net Present Value (NPV) are used to evaluate the economic potential of control opportunities fer an organisation. The results indicate that financial benefits of advanced process control strategies can be predicted, quantified and then evaluated, with the ultimate aim of improving the overall financial position of all organisation.

Implementation of a Profibus agent for the Proview process control system / Implementering av en Profibus-agent i Proview styrsystem

Hauck, Ferdinand January 2009 (has links)
<p>Proview is an open source system for process control, developed at SSAB Oxelösund. A wide range of IO systems are already supported by Proview. This thesis documents the implementation of support for the Profibus DP master board Hilscher CIF 50-PB.</p><p>Most of the features of the board are supported by the agent. The agent is intended to support up to four boards per system. Adding support for additional types of Profibus DP master boards from Hilscher to the agent should be straightforward.</p><p>This thesis covers some technical aspects of the Profibus DP technology and also provides some background of Proview’s IO system. The design decisions behind the Hilscher agent implementation will be discussed. All functions and data structures of the implementation are documented. Testing of the implementation is also included in the thesis.</p><p>The thesis may also be used as technical documentation for the agent implementation.</p><p>Finally, we look at the strengths and shortcomings of the completed agent implementation.</p>
