It is essential for engineers to have an understanding of the nature of the dynamic
behavior of systems, as well as the available methods for analyzing and improving
their stability and precision. As for mechanical engineers, they should be able to deal
with the analysis and design of dynamic systems of different physical nature. A
simple electro-hydraulic servo-valve, for example, includes electric, magnetic,
hydraulic and mechanical components. Therefore, an increasing proportion of
engineers should be acquainted with the modeling of the multi-disciplinary systems
as well as the fundamentals of control theory.
