知的PID制御系の比例・微分先行型への拡張とFRITの適用

抄録

In this paper, we propose a method to achieve a given desired tracking property with only minimal information on the control target by combining FRIT with some extensions to the intelligent PID control system. The intelligent PID control system has a simple structure and can stabilize a system using only parameters without requiring much dynamic characteristics of a control target. Here we firstly extend the intelligent PID to Proportional differentiel leading typed PID controller, which is abbreviated as iI-PD controller, to guarantee the stability of the closed loop for broader class of plants compared with the original inteliggent PID control systems. Secondly, we apply FRIT to decide the parameters of a controller with only one-shot experiment to follow the desired response. Thus, by combining FRIT, we obtain controller parameters which is adjusted so that it enable not only output to follow the desired response but also guarantee the stability of the closed loop system with only an initial experimental data. We also verify the effectiveness of the proposed method with numerical examples.
