Program systems and control

Principal investigator:

Prof. Dr. Stanko Strmčnik

Duration:

January 1, 2004 - December 31, 2008

Funding:

ARRS - Slovenian Research Agency, P2-0001

Abstract:

The operation of modern systems and processes is largely based on embedded control technology, which integrates knowledge from control and systems theory, electronics, computer and information sciences, systems engineering and also knowledge from target application domains.

The key objective of the underlying research programme is to contribute new methods and technical solutions for applications, which are expected to bring benefits in terms of better quality, efficiency and reliability as well as improved design, commissioning and use of control systems.

The programme is composed of four major subprojects:

  • COMPLEX SYSTEMS CONTROL

Most processes can be controlled by relatively simple and standard control methods. Unfortunately there are also processes, which are rather complex regarding their dynamics and uncertain behaviour. The focus within this subproject will be on research and application of nonlinear, predictive, self-tuning and adaptive control, able to cope with these problems. The applications on chemical processes, power systems and - in particular - wastewater treatment plants are foreseen.

  • FAULT DETECTION AND ISOLATION

On-line condition monitoring of products and processes is getting essential in modern production systems. Research in this field will concentrate on design of diagnostic systems robust to modelling errors. Particular endeavour will be paid to the application of advanced nonlinear signal processing techniques for extraction of features that proved useful in a range of industrial problems. The algorithms will be evaluated on laboratory test rigs and in the frame of demonstration applications in industry.

  • COMPUTER INTEGRATED PRODUCTION

One of the main issues in industry today is appropriate integration of the control processes on the physical (equipment) level, production level and business level. This is a hot topic, which is receiving a great deal of attention right now. Our work will concentrate on problems related to mastering the life-cycle of (integrated) control systems, to production decision support systems, to production scheduling algorithms, and to non-technical aspects of control and IT systems introduction. Research will be carried out in the close co-operation with several industrial partners in Slovenia.

  • DEVELOPMENT OF ADVANCED IMPLEMENTATION TECHNOLOGY

Control systems implementation is heavily based on mastering the appropriate implementation technology. Our focus will be on development of special-purpose modules for industrial programmable logic controllers (PLC's), on tools for more efficient implementation of advanced control algorithms, tools for better production control and on automatic code generation for PLC's.
