未知むだ時間系に対する応答予測を用いたデータベース駆動型PID制御器の設計

抄録

In designing database-driven PID control systems, the offline learning scheme of PID gains included in the database has been proposed. However, it is difficult to apply this conventional scheme to real systems with unknown time-delays. In this study, a design method of database-driven PID controller using the response prediction is newly proposed. Plural databases are prepared corresponding to different time-delays and rise times. Furthermore, data-driven response predictive method is also introduced to predict responses and time-delays for each databases. As a result, the database with the desired control performance for the controlled object is adopted. The effectiveness of the proposed scheme for unknown time-delay systems is numerically verified in simulation examples.
