This chapter delineates the path we have chosen for our control engineering journey.

In particular, this chapter contains

an industrial motivational example,
a statement of the fundamental nature of the control problem,
the idea of inversion as the central ingredient in solving control problems, and
evolution from open-loop inversion to closed-loop feedback solutions.
