2.1 Preview

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

In particular, this chapter contains

  • an industrial motivational example,

  • the idea of inversion as the central ingredient in solving control problems, and

  • evolution from open-loop inversion to closed-loop feedback solutions.
