Improving Monitoring Accuracy of process Based on SPC Method

摘要：

In order to improve the monitoring accuracy for the control variables in the production process, a new method to use statistical process control (SPC) was proposed, which analyzed the production process data by the SPC. It can extract the main features of the process variable, and set up the upper and lower monitoring limits for the production process. The decision-making basis for the operator can be provided by monitoring control accuracy of the production process. With this method, it can improve the control accuracy of the process variable and provide the information quickly and efficiently for the fault diagnosis of production process. An on-line monitoring system was designed for the distillation process as an example, and the effectiveness of this method was illustrated.
