Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The block OnOffController sets the output signal y to true when the input signal u falls below the reference signal minus half of the bandwidth and sets the output signal y to false when the input signal u exceeds the reference signal plus half of the bandwidth.

Parameters (2)
