Simulation of On-Off Control with Hysterisis: How it works

Description| How it works



This app works by calculating the values of the process and the controller output every second. The calculation of the process value is similar to that in the PID simulator app. The On-Off controller with hysteresis is modelled as follows:

If Process Value > Set Point + Hysteresis then Controller Output = 1 (ON state)

If Process Value < Set Point - Hysteresis then Controller Output = 0 (OFF state)

If Process Value is in between (Set Point + Hysteresis) and (Set Point - Hysteresis) then Controller Output = previous Controller Output
