Abstract: |
Control of real industrial
processes is almost always burden with an uncertainty. The reasons of that
unfavorable fact are mainly an imprecise modelling
and measuring or an influence of some external conditions. A convenient tool
for dealing with such class of issues represents the application of models
with parametric uncertainty. The mathematical model is then supposed to
contain parameters which are not precisely known,
but the values thereof lie within given intervals. If individual uncertain
coefficients (in polynomial, in transfer function etc.) are mutually
independent, the uncertainty has a simple interval structure. This
contribution offers several possibilities of utilization of interval
uncertainty for systems description and presents the tools for robust stability
analysis, emphasizing advantages and limitations connected with the use of
this simple structure, even for more complicated problems. |
