modelPBand
Information
Proportional band management around a setpoint value.
Hypothesis and equations
It returns a value that varies proportionally with the difference X - X_ref (setpoint). The signal is saturated at Ymin and Ymax in extreme conditions.

Instruction for use
The model setup is:
- Ymin et Ymax, saturation values (eg. 0 and 1 to obtain a gain).
- Value of the Range, i.e. half bandwidth size
Note : For Range > 0, the proportional band will be decreasing. For an increasing function, all you need is Range < 0, leaving other values unchanged.
Known limits / Use precautions
none
