Fractional order PID control of a motion platform

In this paper, the fractional order PID (FOPID) control scheme of a 3-axis motion platform is proposed. Firstly, a mathematical model of the 3-axis motion platform is derived, then a control law is developed to track the angular position. Tuned FOPID controller is compared with classic PID controller (IOPID). The simulation results are provided to verify the efficiency and correctness of the proposed control algorithm.
