Design of fractional-order proportional-integral-derivative controller: Hardware realization

The aim of this paper is to present the implementation of Fractional-Order Proportional-Integral-Derivative (FOPID) to control the step response of the first-order circuit. With FOPID control, we obtain a satisfying result. The FOPID controller outperforms the classical integer PID, wherein both of them are optimized with the Nelder-Mead method. The FOPID controller succeeds to regulate the output of the system to our desired set point with better settling time and rise time than the classical one. In addition, hardware realization is presented with Arduino Uno.
