Phase Plane Analysis of Feed Back Control System having Two Nonlinear Gain Elements.

摘要

one lf the formidable problems in the area of feed back control concerns the analysis and synthesis of nonlinear systems, and several methods have been employed for treating feed back control system with nonlinear elements.This paper describes a method of transient analysis of second order feed back control system having two nonlinear gain elements and subjected to step input. The techniques elements and, essentially, decomposition of the phase plane into regions within which trajectories converges to corresponding critical points.
