In this paper, PID controller design was performed according to a reference model for a fractional order system. The main purpose of the study is to obtain PID controller parameters according to a desired time response in the output signal. It is aimed to obtain the optimum PID parameters by minimizing the error between the reference model and controlled system. Integral performance criteria were used to minimize the error. The reference model is a transfer function of a second order system. </span> <span style="font-size:11pt;line-height:107%;font-family:Calibri, ’sans-serif’;"> </span> <span style="font-size:11pt;line-height:107%;font-family:Calibri, ’sans-serif’;">This transfer function has two parameters that need to be set. </span> <span style="font-size:11pt;line-height:107%;font-family:Calibri, ’sans-serif’;"> </span> <span style="font-size:11pt;line-height:107%;font-family:Calibri, ’sans-serif’;">These parameters are natural frequency ( <i>ω <sub>n </sub> </i>) and damping ratio (ζ).
