Online Monitoring for Industrial Processes Quality Control Using Time Varying Parameter Model

A novel data-driven soft sensor is designed for online product quality prediction and control performance modification in industrial units. A combined approach of time variable parameter (TVP) model, dynamic auto regressive exogenous variable (DARX) algorithm, nonlinear correlation analysis and criterion-based elimination method is introduced in this work. The soft sensor performance validation...

The quality control chart for monitoring multivariate autocorrelated processes

Previously, quality control and improvement researchers discussed multivariate control charts for independent processes and univariate control charts for autocorrelated processes separately. We combine the two topics and propose vector autoregressive (VAR) control charts for multivariate autocorrelated processes. In addition, we estimateAR(p) models instead ofARMAmodels for the systematic cause...

Online Real-Time Water Quality Monitoring and Control System

This research project looks at a novel method for monitoring and control of swimming pool parameters. A National Instruments Compact Rio embedded controller and its software program LabView is used as the basis for this system. A swimming pool model was selected to trial the system due to its similarities with both drinking water and industrial plants. The system monitors the following water pa...
