This paper is a study of the effect of a nonlinear compensation network on the closed-loop response of a feedback control system.

Physical energy dissipation elements, unlike their usual mathematical models, are often nonlinear. An example of such a nonlinear element is the mechanical damper. Since dissipation elements are used in most types of compensation, the problem of nonlinear compensation is an important one.

The study was performed with two goals in mind. The first was to determine the detrimental effects resulting from the insertion of the nonlinear network. The second was to see if any improvement in system performance could be realized by the insertion.

In order to keep the problem within reasonable limits and to obtain definite results, a specific example was considered. An electrical system was used, but the results of the study can be extended to other types of systems by means of the various sets of physical analogies.
