Abstract
Simulation of feedback control systems is a critical step in modern control engineering, providing designers and researchers with a virtual environment to validate control strategies before hardware implementation. This manuscript presents a comprehensive study of feedback control system simulation using MATLAB/Simulink, emphasizing techniques and best practices available up to 2014. The abstract outlines the purpose, scope, methodology, key findings, and conclusions of the work. The study covers the modeling of standard feedback configurations, simulation setups, and analysis of system performance under varied conditions. Three case studies—temperature control of a first-order thermal process, speed control of a DC motor using PID, and vibration suppression in a mass-spring-damper system—demonstrate the applicability of MATLAB/Simulink block diagrams, parameter tuning techniques such as Ziegler–Nichols, and time-domain analysis. Methodology includes block-diagram modeling, simulation configuration, parameter selection, and performance metrics evaluation. Results indicate that properly tuned PID controllers achieve settling times within 5% of design specifications and overshoot less than 10%. Conclusions stress the value of simulation in reducing design cycles and ensuring robustness. Ten references from works published up to 2014 are provided.
