A STUDY ON EFFECTIVENESS OF USING FREQUENCY RESPONSE METHODS IN A CONTROL SYSTEM

In the field of electrical engineering, control systems are extremely significant. It is difficult to study and construct electrical networks comprehensively without them. Using root locus (time domain) and frequency response (Bode Plots) strategies, this paper successfully tries to model a realistic real-world control device. The root locus and Bode plots are briefly discussed. The controller architecture and how the necessary aim requirements can be met have received a lot of attention. MATLAB has only ever been used for simulation and architecture. Control systems are designed to change the behaviour of an existing device so that it can function as intended. There are some scenarios of real life where such control actions are required to produce the desired outcomes. The air-conditioning system consists of elements that change the current temperature (also known as actuators because they operate on the mechanism), sensors that calculate the current temperature, and control logic that determines which actuation to do in order to reach the target temperature. In this segment, we'll go into the fundamentals of control systems, their effect on real-world systems, and how they're designed to change the behaviour of a given plant to meet precise requirements. One of the most important and difficult areas in the modern century is feedback management. It is taught in almost every technical programme. The study of input control mechanisms has been the subject of several studies. This paper uses MATLAB to do a complete study of feedback control systems, including transition functions, poles and zeros, device consistency, initial and final values, state space representations, various responses of a system, time reaction of first and second order systems, Routh-Hurwitz criteria, root locus, and Bode map.
