Arrangement for predicting an abnormality of a system and for carrying out an action which counteracts the abnormality
First Claim
1. An arrangement for predicting an abnormality of a dynamic system and for implementing an action opposing the abnormality using a continuous information flow that describes a development of a predictability of several future system states, comprising:
- a) a measured data pick-up that registers comparison measured data of said system and test measured data of said system;
b) a processor unit, having a neural network that models said system, said processor unit(1) training said neural network using said comparison measured data;
(2) determining a comparison information flow that describes a comparison dynamic of said system using said trained neural network;
(3) determining a test information flow that describes a test dynamic of said system using said test measured data;
(4) using said comparison information flow and said test information flow, predicting said abnormality as established when said comparison information flow differs significantly from said test information flow, and predicting said abnormality as not established when said comparison information flow does not significantly differ from said test information flow;
(5) when said abnormality of the system has been predicted as established, then implementing said action; and
c) an actuator that implements said action,wherein the information flow describes a development of a predictability of plural future system states.

Abstract
An arrangement and method are presented that enable a prediction of an abnormality and implement a suitable action opposing the abnormality. An information flow underlying a dynamic system is interpreted and a prediction quantity that comprises the abnormality as characterizing quantity of the dynamic system is determined from it. A neural network is trained with measured data of the system. After the training, the abnormality can be indicated on the basis of the prediction quantity before it occurs and the occurrence can be opposed with suitable measures.
