Feedback control systems are among the most important and complex areas in modern engineering and are a core part of almost every technical curriculum. While extensive research has been conducted in this field, much of it has traditionally focused on system analysis using individual approaches such as stability criteria, initial and final value theorems, state-space representation, root locus, and Bode plots. A control system consists of interconnected components designed to produce a desired output. Open-loop systems operate without feedback, relying on controllers to achieve the required response, whereas closed-loop systems continuously compare actual output with the desired output to improve accuracy and performance. Feedback systems are widely used in applications such as oscillators and electrical systems, helping maintain system stability and desired characteristics.
