There are several books published on robust control. Most focus on a

particular approach. These books are most suitable for researchers specialized

in the particular area and techniques. I often have trouble understanding

the theoretical underpinnings of these books. From my contacts

with control engineers in the automotive industry who try to solve very

practical problems, I learned that they too have trouble understanding these

books. Furthermore, engineers will not be able to determine which approach

could be the best for the problems at hand before they fully understand the

numerous methods available to them.
