This section is written to introduce the reader to nonlinearity and its effect in control systems, and also to 'set the stage' for the subsequent articles. Nonlinearity is first defined and then some of the physical effects which cause nonlinear behaviour are discussed. This is followed by some comments on the stability of nonlinear systems, the existence of limit cycles, and the unique behavioral aspects which nonlinear feedback systems may possess. Finally a few brief comments are made on designing controllers for nonlinear systems.
