On Off Controller

On-off controller

 Description The On Off Controller component sets the output signal $y$ to $\mathrm{true}$ when the input signal $u$ falls below the $\mathrm{reference}$ signal minus half of the hysteresis and sets the output signal $y$ to $\mathrm{false}$ when the input signal $u$ exceeds the $\mathrm{reference}$ signal plus half of the hysteresis.
 Equations $y=\left(\mathrm{pre}\left(y\right)\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}\mathbf{and}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}u<\mathrm{reference}+\frac{\mathrm{hysteresis}}{2}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}\mathbf{or}\phantom{\rule[-0.0ex]{0.3em}{0.0ex}}u<\mathrm{reference}-\frac{\mathrm{hysteresis}}{2}\right)$
