Modern day control engineering (also called control systems engineering)
is a relatively new field of study that gained a significant attention
during twentieth century with the advancement in technology. It
can be broadly defined as practical application of control theory.
Control engineering has an essential role in a wide range of control
systems from a simple household washing machine to a complex high
performance F16 fighter aircraft. It allows one to understand a
physical system in terms of its inputs, outputs and various components
with different behaviors using mathematical modeling, control it
in a desired manner with the controllers designed using control
systems design tools, and implement the controller on the physical
system employing available technology. A system can be mechanical,
electrical, fluid, chemical, financial and even biological, and
the mathematical modeling, analysis and controller design shall
be done using control theory in one or many of the time, frequency
and complexs domains depending on the nature of the control system
design problem.  Wikipedia
