The effect of main nonlinearities on servo systems stability

Abstract EN

Servo systems are indispensable in modern industry.

For example, they are widely used in robotics, electrical vehicles and automated factories.

Therefore, the study of the stability of the system and its response to linear and nonlinear elements is an important control system problem.

This paper focuses on determination of servo system transfer function and the effect of the main nonlinearities on its stability by developing an algorithm for the system and simulating using MATLAB.

The algorithm used is the describing function algorithm and its analysis ,since it is one of the methods used to analyze nonlinear systems stability.
