Control structures for variable inertia output coupled drives

The control of output coupled drive systems with a variable moment of inertia is difficult due to the effects of output coupling of control sub-systems, elastic coupling, and variability of plant parameters. Typical examples of such applications include rolling mills, winding mechanisms and electrically driven transportation systems. The paper deals with pointing out the thematic and giving results concerning the development of conventional and fuzzy control structures for two output coupled electrical drives applicable to the rolls of a rolling mill and to a variable inertia strip winding system.
