Modern control theory application in mill main drive design

Modern Control Theory is applied to analyze an existing aluminum mill drive, which was originally designed by Classical Methods.

The system is studied with Optimal Control and z-transform zero-pole locus tools.

The results and also the original design are compared with the performance of simulation. The models are built with the transition matrix and iterative procedures.

Conclusions about the appropriated design methods and improvements to the control scheme result from the investigation.
