The thesis assignment was to build a PID control that was able to control two tanks of water. The system had to be capable of read a certain value, the value that we speak is the high of the water. There for, the system should fill the corresponding tank with water, of course, until the high that was chosen. A PID control uses tree essentials values to be able to control with precision, they are usually called: P, I and D. These values can be found by applying some procedures; in this thesis two procedures were applied. So at the end, we get two values for each constant (PID). In this thesis these two values are compared in order to choose which method was the accurate.
