データ指向型スマート適応制御系の一設計

摘要

近年，プロセス産業界においては，国際競争の激化やエネルギー問題などから，生産性や品質の向上，省エネルギー化•省力化などが進められており，制御システムが果たす役割は，これまで以上に重要視されてきている.%Data-roriented controllers are emerging as an alternative to model-based controllers designs, due to the fact that data-roriented controllers enhance the closed-loop behavior of the system by using very simple structures. This paper studies how to evaluate the control performance of a closed-loop data as well as how to adjust the control parameters to improve the control performance. PID control method based on Generalized Minimum Variance Controller (GMVC) is considered. When the control performance is deteriorated due to changes in control parameters, the closed-loop data are utilized to re-adjust the direct system parameters. Simulation results are provided to demonstrate the effectiveness of the proposed control scheme.
