基于多步延迟自动反馈控制的过程质量监控

Statistical quality monitoring of multiple steps delay feedback controlled processes

研究了具有多步延迟特性的反馈控制进行自动过程调整后的质量监控问题.建立了多步延迟自动反馈控制的过程质量监控模型,分别给出了基于多步延迟的MMSE控制器反馈调整后对过程输出和调整量两种数据流建立的控制图平均运行长度的计算方法,用以评价控制图的效率.最后通过一个简单的算例说明该方法的使用.

This paper discusses the quality monitoring of multiple steps delay feedback controlled processes. A quality control model based on multiple steps delay feedback controlled processes is set up. And the calculating method of average run length of control charts based on process output and control action of multiple steps delay MMSE feedback controlled processes is provided to evaluate control charts performance.A simple example is used to illustrate the procedure of this approach.
