Description
The “Control Loop” library includes function blocks for process control. It consists of different elements that are assembled flexibly into a control structure. These include various differentiators and integrators, for which various anti-windup strategies are available. In this way, the structure of the created control can be derived from the selected components. Some transfer functions are also achieved according to this scheme. This library also provides an example for the use of nested object-oriented function blocks.
The library also contains several digital filters that can be used for signal processing. For this purpose, it is necessary to determine the rating parameters yourself.
