The Engineering Pilot plant at Murdoch University is one of the unique process facilities that currently exists in any universities in Australia. It provides an opportunity for Instrumentation and Control engineering students studying at Murdoch University to explore various control methods and strategies to extend their range of knowledge in this area with the aid of physical instruments and software provided in the pilot plant.

The purpose of this thesis project is to devise a strategy to improve the process measurements in the pilot plant through investigation of theory and implementation of Steady State Data Reconciliation and Online Dynamic Data reconciliation and to observe and testify if data reconciliation can improve process control performance with a more accurate set of measurements

This project has been divided into three different stages with the first stage being, the understanding of data reconciliation, understanding of DR using existing case studies, followed by the investigation of the physical implementation and foundation work of data reconciliation in the pilot plant, and finally the testing and conclusion as to whether or not data reconciliation can improve the process measurements and consequently the control results.

Results of the implementation of data reconciliation indicated the improvement of process measurements. Non-Linear Tank and Needle Tank have shown considerable measurement improvement with the implementation of data reconciliation on the measuring variables of both tanks. Flow rate in, flow rate out, and levels of both tanks were monitored and measured except the flow going into Non-linear Tank were estimated as there were no measuring device available for that particular variable.

Ball Mill Tank and Cyclone Underflow Tank were also investigated with a recycle stream, steady state data reconciliation have also been implemented at this process system and helps to improve a better understanding of data reconciliation applications.

Dynamic data reconciliation were also implemented at the Needle Tank in the pilot plant for case study investigation, the results obtained is of what was expected and proved that DDR can provide significant contribution in terms of improving process control performance of the process system in the future.
