Hysteresis
Transform Real to Boolean signal with Hysteresis
Library
Modelica/Blocks/Logical
Description
This block transforms a Real input signal into a Boolean output signal:
- When the output was false and the input becomes greater than parameter uHigh, the output switches to true.
- When the output was true and the input becomes less than parameter uLow, the output switches to false.
The start value of the output is defined via parameter pre_y_start (= value of pre(y) at initial time). The default value of this parameter is false.

mo_uHigh | uHigh | if y=false and u>=uHigh, switch to y=true | Scalar | |
mo_pre_y_start | pre_y_start | Value of pre(y) at initial time | Scalar | true |
