Closed Loop Control

In many industrial plants, one or more physical/chemical variables must follow a predetermined change over time so that the product of the plant exhibits the desired property and the plant does not enter a critical/dangerous state. The challenge in developing such software solutions is that in most cases not only a functional description of the plant and programming knowledge of the respective PLC platforms are sufficient. What is needed is a deep knowledge of the physical laws that prevail in the plant. In addition, the know-how about the control-technological investigation and its realisation must be available.
