This paper presents a low-cost experimental platform for real time data acquisition, identification and fractional order control of some low dynamic systems via Arduino-Simulink interface. As a demonstrative example, a DC motor is considered and modelled as a First Order Plus Time Delay Plant (FOPTD) using data acquisition-based Arduino. Then, simple analytical rules are used to design a robust Fractional Order Controller (FOC) which require a high computing power. Several validation tests of the FOC have been curried out via Arduino–Simulink interface. The experimental results, compared with those obtained with theoretical simulation; confirm that the proposed interface can be used to support research and teaching feedback control systems via experimental investigations on a low-cost laboratory kit.
