ABSTRACT:
An open-loop and closed-loop control method is described for starting up or shutting down a process component of a technical process. At least one manipulated variable that is fed to the process is formed by a control device and an upstream model-assisted pilot control. The pilot control contains an optimizer and a process model. The optimizer is fed at least one command variable for the technical process. At least one optimized model manipulated variable which the optimizer outputs is fed to a process model of the pilot control and, is added to at least one output variable of the control device to form the manipulated variable. A model output variable of the process model is fed to the control device as a set-point and fed back to the optimizer along with variables which cannot be measured in the technical process. A device for implementing the method is also described.
