Abstract: A method for real-time calculation of state variables (xM) of a process model on a process computer with a first calculating unit and a process interface, wherein the computer is designed so that at least one state variable of a physical process can be received by the computer using the interface and/or at least one output variable for controlling the process can be issued by the computer, wherein the model is calculated by the first calculating unit with an explicit integration method for determining the state variables. According to this method, a second calculating unit is provided, the model is carried out with the second calculating unit using an implicit integration method essentially simultaneously with the calculation of the model with the first calculating unit and the state variables (xM,i) calculated with the second calculating unit and the implicit method are used as state variables (xM) of the model.

Abstract: A method for real-time calculation of state variables (xM) of a process model on a process computer with a first calculating unit and a process interface, wherein the process computer is designed so that at least one state variable of a physical process can be received by the process computer using the process interface and/or at least one output variable for controlling the physical process can be issued by the process computer, wherein the process model is calculated by the first calculating unit with an explicit integration method for determining the state variables. According to this method, a second calculating unit is provided, the process model is carried out with the second calculating unit using an implicit integration method essentially simultaneously with the calculation of the process model with the first calculating unit and the state variables (xM,i) calculated with the second calculating unit and the implicit method are used as state variables (xM) of the process model, insofar as the state variables (xM,i) calculated with the second calculating unit and the implicit method exist in real time and otherwise, the state variables (xM,e) calculated with the explicit integration method are used as the state variables (xM) of the process model. The present method prevents—at least partially—the presented disadvantages in the known method for real-time calculation of state variables of a process model and ensures the real-time capability of the calculation while guaranteeing as much as possible the numerical accuracy and stability of the calculation.
