In this paper, an iterative PID controller design method with unfalsified control theorem and extended L2 gain criterion is considered. The design method utilizes fictitious reference signal which is derived from plant input-output data for candidate controller falsification. The proposed design method includes a procedure for adjustments of the performance specification which leads to the improvement of the convergence property. The effectiveness of the proposed method is evaluated by experiments on a magnetic levitation system.
