The role of transfer function in the study of stability analysis of feedback control system with delay

Abstract

Loop delays appear obviously in several control applications. Due to loop delays, more complications arrive in feedback control systems. Loop delays cannot be avoided in a system controlled via communication networks as it decreases the stability of the system and restricts the achievable response time of the system. The transfer function is a main tool for analyzing and designing the feedback control system. It describes the system's input output behaviour. In this paper, we have examined the stability of feedback control system using transfer function.
