控制系统性能评估技术发展综述

Review of Development of Control System Performance Assessment Techniques

对控制性能评估(CPA)技术的研究已有近三十年。因CPA在保证控制系统高效、稳定运行方面的显著特点,一直受到学术和工业界的关注。特别是随着工厂所用控制系统的升级和完善,工业过程数据的存储和利用更为方便。这些丰富且包含大量价值的数据成为推动CPA技术发展的重要基础。首先,从控制回路中性能下降的原因分析出发,阐述了性能评估的主要任务和作用。然后,对CPA领域发展比较完善的评估部分,整理综述了多种性能评估指标的研究现状。最后,为便于对该领域感兴趣的研究者入手研究,简要介绍了四种用于CPA的公开数据库,并对CPA技术的发展趋势进行了展望。

Research on control performance assessment(CPA)techniques has been conducted for nearly three decades.Because of its remarkable features in ensuring efficient and stable operation of control systems,CPA has been receiving attention from both academia and industry.Especially with the upgrading and improvement of control systems used in factories,the storage and utilization of industrial process data has become more convenient.These rich and valuable data have become the important basis for the development of CPA technology.Firstly,the main tasks and roles of performance assessment are described from the analysis of the causes of performance degradation in control loops.Then,for the assessment part of the CPA field,which is relatively well-developed,the research status of various performance assessment indexes is organized and reviewed.Finally,in order to facilitate the entry of researchers interested in this field,four publicly available databases for CPA are briefly introduced,
