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.
