I am trying to model a rainwater harvesting system using Simscape. Currently I struggle to control my treatment unit. In case the water volume of the treatment's subsequent tank reaches a certain level, I want to pause the treatment. I am doing this by sending a signal to the pressure source advancing the treatment. If the treatment is meant to pause I simply set the implied pressure difference to zero. Now, whenever I hit my threshold and the system is meant to pause, it hangs-up.
I tried to do the sharp change manually. It worked fine. However, I want my system to run automatically.
I tried a lot of different things but to be honest, I don't really know or find the problem. I reckon it is associated with the signal to control the implied pressure, but how?
Any help and/or note is appreciated.
