Sometimes, it is possible to describe the operation of a physical system by a linear model, e.g., as a set of ordinary linear differential equations. This is the case, for example, if the mode of operation of the physical system does not deviate too much form the nominal set of operating conditions, i.e., one can linearize the system. Thus, the analysis of linear systems occupies an important place in system theory. But in analyzing the behavior of a physical system, one often encounters situations where the linear (or linearized) model is inadequate or inaccurate; that is the time when concepts of this solution may prove useful.
