Abstract—Auto tuning PID controller is designed using MATLAB, Simulink and Graphical User Interface (GUI) as well as the optimization of PID controller without excessive mathematic calculations. Ziegler-Nichols second method is used for designing purpose of the auto tuning PID controller. Some drawbacks have been discovered using this technique, where in some cases analysis and design problems can be tedious, since the solution involves trial and error. There are other methods utilized to solve this problem by given access to computers or programmable calculators configured with appropriate MATLAB and GUI software. The true power and advantage of the program developed lies in its ability to represent both compensated and uncompensated relationship and also ability to learn these relationships directly from the data being modeled. The results will then being validated by using manual calculation, MATLAB and Simulink. The value of Kp, Ti and Td in Ziegler-Nichols formula will be calculated using manual calculation while step response graph for each cases will be solved solve using Simulink.
