The design of nonlinear filters and control systems part II

Abstract

This part of the paper is devoted to an exploration of the applicability of the theoretical method developed in Part I to analytical and experimental examples. It is shown that the method has limited utility in analytically interesting examples but that, through judicious use of modern computation machinery, numerical solutions to real, physical problems appear to be feasible-but difficult and involved. An experimental application of the theory to the characterization of the servomechanism associated with the pupil of the human eye is described. Emphasis is placed on the utilization of known properties of the experimental system in planning the computation. A measure of the complexity of the computation is developed in order that the practicability of applying the method in a given situation may be judged in advance. © 1964 Academic Press Inc.
