Dynamic Analysis and Monitoring of Process Control Loops
نویسنده
چکیده
Dynamic analysis and monitoring is of great importance in industrial process plant. Very often, a qualitative analysis of process data is enough to analyze the situation of the plant. This paper introduces a methodology to analyze qualitative trend of time series data at first. Based on the methodology, a method to diagnose a control valve in a process control loop is introduced. The proposed diagnosis method is successfully applied to several data sets in industrial chemical processes.

A risk adjusted self-starting Bernoulli CUSUM control chart with dynamic probability control limits
Usually, in monitoring schemes the nominal value of the process parameter is assumed known. However, this assumption is violated owing to costly sampling and lack of data particularly in healthcare systems. On the other hand, applying a fixed control limit for the risk-adjusted Bernoulli chart causes to a variable in-control average run length performance for patient populations with dissimilar...
متن کاملA DMAIC approach for process capability improvement an engine crankshaft manufacturing process
The define–measure–analyze–improve–control (DMAIC) approach is a five-strata approach, namely DMAIC. This approach is the scientific approach for reducing the deviations and improving the capability levels of the manufacturing processes. The present work elaborates on DMAIC approach applied in reducing the process variations of the stub-end-hole boring operation of the manufacture of cra...
