Internal Model Control of Grinding Circuits: An

1989-9-1  Internal Model Control schemes are attractive approaches to the automation of industrial multivariate processes. The technique is tested here for a simulated two-stage grinding circuit. The circuit operation is modelled using a 2x2 transfer matrix which represents the internal model to be controlled.

Process Control in Internal Grinding ScienceDirect

1980-1-1  Internal grinding is a cost intensive process in mass production such as in automative and bearing manufacture. The abrasive process has to be maintained under unfavourable conditions with a great extent of reliability and with high rates of productivity. A cost analysis of a typical production task shows the relevance of rationalizing measures.
