Abstract :
The present study discusses a model-free design method for control systems using fictitious reference input tuning (FRIT), which was originally designed based on one-shot control data. Moreover, FRIT has been extended to an online tuning method to cope with plant fluctuation. In the present study, the control quality is monitored using online FRIT. In the conventional online FRIT, the control system is always updated. In the proposed method, performance evaluation is introduced to the online FRIT. Consequently, quality monitoring can be implemented by online FRIT, and a control system can be updated only when a controlled plant fluctuates or the control performance deteriorates. The effectiveness of the proposed method is demonstrated through numerical examples.
