Patent attributes
A process control system for controlling at least one process actuator includes a first process model for driving at least one process actuator in such a manner that at least one process desired manipulating variable is generated for driving at least one process actuator; a second process model, which generates a process actual variable from at least one process actual manipulating variable of the at least one process actuator; and another process element for generating a comparison process actual variable. The first process model can be mapped by inverting the second process model, and a process actual variable difference, which is formed from a process actual variable and a comparison process actual variable, is fed via a control unit to the first and second process models. The process element is designed as a third process model with higher reproduction precision and includes at least one non-invertible process component.
