  • Method and device for determining a fault in a technical system
    Patent number: 6556954
    Abstract: A technical system that is subject to a malfunction is described with an implicit stochastic differential equation system. An approximative solution of the system is determined in that a discrete approximation process is realized. The discrete approximation process is realized according to the following rule: −(C+h&agr;2G)·{tilde over (X)}&pgr;n+1={−(1−&ggr;)C+h(1+&ggr;&agr;1−&agr;2)G}·{tilde over (X)}&pgr;n+ +{−&ggr;C+h(&ggr;−&agr;1&ggr;)G}·{tilde over (X)}&pgr;n+1 +h&agr;2s(&pgr;n+1)+h(1+&ggr;&agr;1−&agr;2)s(&pgr;n)+ +h(&ggr;−&agr;1&ggr;)s(&pgr;n−1)+ +B(&pgr;n)·&Dgr;Wn+&ggr;B(&pgr;n)·&Dgr;Wn−1 The disturbance {tilde over (X)}&pgr;n+1 is determined by iterative solution of the approximation process.
