  • Spatial loopshaping tuning for consistency profile control

    Publication Year: 1999, Page(s):50 - 57
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (384 KB)

    In this paper, recent developments in control of spatially-invariant processes are applied to an industrial problem of cross-directional profile control in papermaking. The process is approximated in terms of a spatial frequency decomposition which allows the extension of traditional techniques of loopshaping to the two-dimensional dynamical and spatial frequency domain. The designed controller is... View full abstract»

    This paper describes how QuickStudyTM, a model based adaptive process controller, was used to solve a key control problem associated with an acetic acid reactor. The operating company had achieved greater production rates and efficiency through the use of an improved catalyst but with the penalty of decreased reactor temperature stability. A PID based control strategy became unstable at... View full abstract»

    We describe the planning and development of an artificial neural network model of line 3 of the Copper/Lead/Zinc flotation circuit at Brunswick Mining's concentrator at Bathurst, New Brunswick. The prototype model predicts the copper and lead assays of the concentrate streams of this rougher flotation circuit. In the model, the actual values and rates of change in the main process variables such a... View full abstract»

    The key driver for open software based controls, is the ability for products from multiple vendors from both inside and outside the industrial control arena to coexist and integrate on the same platform. Potential users are faced with a critical decision regarding the operating system strategy for open PC-architecture-based-control. Various alternatives exist in the marketplace ranging from real-t...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (352 KB)

    Trans Mountain owns and operates approximately 1300 km of pipelines in Alberta, British Columbia and Washington state. These pipelines transport a variety of liquids including crude oils, refined products and methyl tertiary butyl ether. They traverse both very remote areas and highly populated ones, as well as hundreds of creek, stream, and river crossings. Environmental concerns have led us to c... View full abstract»

    An adaptive control system utilizing neural network modeling and genetic algorithms has been successfully installed and tested in a gold processing plant located in Nevada. The principle design parameter of the system was feedrate improvement. After installation and commissioning, the system was able to pay for itself through increased feedrate within two weeks. The control system, utilizing a sel... View full abstract»

    This paper discusses the use of OLE for process control as a medium for connection of third-party applications to legacy control systems. This topic is becoming more important as legacy system users attempt to “open up” their systems to third-party applications. Several approaches to implementing the OLE for process control interface to existing systems are discussed, including emulati... View full abstract»

    The management of electric submersible pumps (ESPs) at well sites can be improved using expert system technology to combine real-time sensor information with production engineering rules. When abnormal conditions exist on an artificial lift well, the problem is not always evident until significant production loss and/or pump damage become apparent. By applying expert system technology, operators s... View full abstract»

    Temperature control of processes that involve the heating and cooling of a closed batch reactor can be a real problem for conventional PID based loop controllers. Tuning can be extremely difficult due to the reduced stability margins proved for these types of processes. This paper describes the application of a new advanced process controller that is designed to handle integrating-type processes w... View full abstract»
