Some criteria for asymptotic stability of linear and time-invariant systems with constant point delays are derived. Such criteria are concerned with the properties of robust stability related to two relevant auxiliary delay-free systems which are built by deleting the delayed dynamics or considering that the delay is zero. Explicit asymptotic stability results, easy to test, are given for both ...

The time delay in transport of material and energy is an inseparable part of many real industrial processes. Unfortunately, the presence of time-delay terms itself almost always brings problems in control and, quite naturally, the situation is even more complicated if this delay is uncertain. The source of the uncertainty can arise e.g. from simplifications during mathematical modelling, change...

Această lucrare tratează problema conducerii robuste a sistemelor liniare cu incertitudine cu argument întârziat ce conţin elemente de execuţie cu saturaţie. Utilizând fundamente teoretice, cum ar fi teoria Razumikhin cu privire la stabilitatea sistemelor cu incertitudine cu argument întârziat, teoria Lyapunov a stabilităţii ecuaţiilor diferenţiale funcţionale, tehnici de optimizare via inegali...
