Summary
The stability of the equilibrium solution of a class of coupled partial differential equations with nonstationary random coefficients is studied. Several theorems in regard to mean square stability of the equilibrium state of the system are established. Some examples of the applications of the results to engineering problems are presented and significant improvements on stability region are observed.
Übersicht
Für eine Klasse von gekoppelten partiellen Differentialgleichungen mit nichtstationären Zufallskoeffizienten wird die Stabilität der Gleichgewichtslage untersucht. Dabei werden mehrere Sätze über die Quadratmittel-Stabilität der Gleichgewichtslage aufgestellt. Die Ergebnisse werden auf Beispiele aus dem Ingenieurbereich angewandt und ergeben bedeutende Vergrößerungen der Stabilitätsgebiete.
