I would like to suggest to check the references from Vachhani et al and their coworkers research on Data Reconciliation for nonlinear dynamical systems.
I think there are some Ref. for your requested topic; hereafter you can find link of some publications (books and papers) it could be helpful:
- Annual Reviews in Control; Volume 36, Issue 2, December 2012, Pages 235–243; Dynamic data reconciliation in mineral and metallurgical plants (http://www.sciencedirect.com/science/article/pii/S1367578812000405)
- Advanced Control and Supervision of Mineral Processing Plants
By Daniel Sbárbaro, René Villar (The Book is enclosed and I think it is a good book)
- Dynamic data reconciliation: From the full model observer to the stationary on-line mass conservatio; Automation in Mining, Mineral and Metal Processing, Volume # 12 | Part# 1 ; (http://www.ifac-papersonline.net/Detailed/31714.html).
