Level control uses the boiler drum as a controlled object, and uses the level as a controller value. By making sure the level control is attached accurately we get better dynamic performance. I use the cascade control to make the difference to the traditional control.
In this thesis, I summarize many problems with the level control in the steam boiler field as the false level phenomenon. I design three methods for the level control process system with different ways. I make the final choice at the end. I also do the SAMA figure to show the systems way of running.
The automation is one of the main points with the level controlling system in the thesis.
At the end of this thesis, I was able to achieve the automatic controlling for the steam level.
