摘要：控制性能评价技术对于保证控制系统的长期稳定运行具有重要意义。致力于基于广义最小方差基准的串级系统性能评价及其应用研究，在给出串级系统的广义最小方差性能评价基准的基础上，针对实验室的水箱液位控制对象，利用DCS系统采集的变量数据进行了模型辨识，进而实现了控制性能的评价。实验结果表明采用广义最小方差准则比最小方差性能评价方法更能反映控制系统的波动情况。

Abstract: Control performance assessment (CPA) is of important significance for control system operation. Generalized minimum variance(GMV)-based cascade control performance assessment was proposed, with its application in pilot water tank level control. Model identification and control were undertaken in DCS platform (JX-300X). At last, the CPA experiment shows a more reasonable indication of fluctuate information with GMV than MV.
Key words: performance assessment; DCS; minimum variance(MV); generalized minimum variance(GMV)
