On/Off control system

Hi all,

My project is to control a water tank system, that is the Motor is ON when the water in the tank reaches below a certain level(Δh) and it motor is OFF when the water level is above the specified level (H).

I have attached the picture of the system below. (motor can be considered as a unity proportional controller).

Any help will be much appreciated. Thank you.

A Relay block can be used to implement this. Alternatively, a Stateflow algorithm can be used, see the folowing resource for more insights:
