Hysteresis
Transform Real to Boolean signal with Hysteresis
Library
Modelica/Blocks/Logical
Description
This block transforms a Real input signal u into a Booleanoutput signal y:
- 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 parameterpre_y_start (= value of pre(y) at initial time).The default value of this parameter is false.
