Rolling Mill - Kalman Filtering
Summary
This is the fourth in the Rolling Mill laboratory series.
This laboratory focuses on the use of Kalman filters to estimate unmeasured disturbances.

The Physical Apparatus
In Laboratory 7 we found that an observer was useful to compensate for the effect of periodic disturbances in the operation of the BISRA thickness estimator in Rolling Mills. This laboratory goes a further step to carry out an optimal design of the observer using Kalman Filtering.
This is the fourth in the Rolling Mill laboratory series. The first Rolling Mill laboratory looked at system modelling and classical control. The second looked at soft sensors and the third looked at periodic disturbances and observer design. The reader is referred to the earlier laboratories for a description of the Rolling Mill system and its function.
Prerequisites
This virtual laboratory examines the more advanced ideas of Kalman Filtering. The reader is advised to be reasonably familiar with the material in the other Rolling Mill laboratories. In particular, for an understanding of periodic disturbances and their compensation via observers the reader is advised to have completed Laboratory 8, Rolling Mill (C).
Learning Objectives
The objectives of this laboratory are:
- To gain appreciation of Kalman Filters as valuable control system design tools.
