摘要：

In the present paper we investigate the problem of digital implementation of retuning fractional-order (FO) controllers for an unstable plant-a real-life laboratory model of a magnetic levitation system (MLS). Retuning control is applied to an existing closed-loop PID control system through the use of a hardware FO controller prototype. An implementation method for the retuning controller is proposed. Two types of hardware-in-the-loop (HIL) experiments are considered-in one case the plant is simulated, and in the other the real-life laboratory model of the MLS is controlled. Three controllers obtained in our earlier work are tested with this setup. Experimental results are compared and discussed.
