Application of Fictitious Reference Iterative Tuning to Controller Design for Various Machines

This paper presents an application of a fictitious reference iterative tuning method (FRIT), which is data-driven controller design method, to various machines. FRIT can be used to design the controller using only the initial experimental data, without the state equations of the model and the model parameters. The proposed controller is based on a PID control and included multi control loop. The control objects are a two-mass resonance system, a ball screw positioning system, a switched reluctance motor, and a switched reluctance generator. Finally, we confirm the effectiveness of the proposed method through computer simulations and experimental results.
