Soldatov V.V., Maklakov V.V., Kamakin V.V. Robust process control in statistical uncertainty conditions

The paper examines the problem of selecting process control criteria whose optimization would minimize energy losses due to controlled variables deviations from setpoints. For linear stationary systems, the location of the dominant roots of the characteristic equation is determined that ensures their robustness. The techniques for standard controller settings calculation based on the derived robustness conditions is offered.

Ovchinnikova T.I., Yefimov S.O., Vlasov S.A., Ghenkin A.L. Computer technologies for innovations in environmental protection and energy conservation in metallurgy

A topical problem of applying information and computer technologies for improving environmental performance and energy efficiency of modern metallurgical production is addressed. With the example of a rolled steel system, the paper demonstrates how the application of simulation techniques could help to solve the problem.

Molchanov A.Yu. The technology of application software development for distributed computing

The paper informs about the commercial availability of program development systems that support two most common technologies for distributed computing application software development. These are the client/server technology that had occupied its market niche rather long ago, and a relatively new technology for multi-tier application development. Features, merits and drawbacks of software development are discussed as well as the principles of applications operation in client/server architectures.

Kroshkin A.N. The functionality of modern flowmeters

A paper dedicated to PROline concept for instrumentation that underlies the evolution of Endress+Hauser flowmeter family was published in Automation in Industry, No 10, 2004. Key components of the concept, such as sensors, transmitters and ancillary devices were reviewed; and it was shown that maximum segmentation of device level, unification of electronic modules and the availability of hard- and software support at all stages of instrument lifecycle ensure their best conformance to users` requirements. This paper provides further discussion of the subject and is dedicated to the implementation of additional functions not typical for conventional flowmeters. Unfortunately, the limited space does not allow to overview all models and possible implementation versions - such information can be found in engineering manuals. The paper provides several most interesting examples that illustrate the development level of these instruments and the flowmetering as a whole in the most popular way without excessive engineering specifications.
