Control system

摘要

The system (1) has a control path (14) and an active controller (36), where the system is hierarchically divided into various levels (10-40). One of the levels represents a complex, real process to be controlled and is implemented by a control path (14). Another one of the levels represents an interface to the process and is implemented by a process control system. The third level represents the control of the process and is implemented by the active controller. The fourth level represents a superior overview and is implemented by a main controller (44).
