THE EFFECT OF MAIN NONLINEARITIES ON SERVO

Abstract

Servo systems are indispensable in modern industry. For example, they arewidely used in robotics, electrical vehicles and automated factories. Therefore, thestudy of the stability of the system and its response to linear and nonlinear elements isan important control system problem. This paper focuses on determination of servosystem transfer function and the effect of the main nonlinearities on its stability bydeveloping an algorithm for the system and simulating using MATLAB. The algorithmused is the describing function algorithm and its analysis ,since it is one of the methods used to analyze nonlinear systems stability.
