Method and device for providing at least one input sensor signal for a control and/or monitoring application and control device

摘要

A method of providing at least one input sensor signal for a control and/or monitoring application (13) regarding an installation (1) is provided. The method comprises the steps of:
- providing at least one real sensor signal based on at least one quantity measured at the installation (1);
- providing at least one dynamical model of the installation;
- estimating states on at least the basis of the at least one sensor signal using the dynamical model;
- generating at least one virtual sensor signal from the estimated states by calculating at least one local condition at the installation from the estimated states and establishing the at least one virtual sensor signal from the at least one local condition;
- providing the at least one virtual sensor signal as the at least one input sensor signal for the control and/or monitoring application (13).
