Abstract: Control systems play a vital role in industrial automation by ensuring stability, accuracy and efficiency in dynamic processes. Among various control strategies, the Proportional–Integral–Derivative (PID) controller is widely used due to its simplicity, reliability and effectiveness in diverse industrial applications. This paper presents a comprehensive review of PID control systems in industrial automation. The study covers fundamental principles, controller tuning methods, industrial applications, implementation challenges and future advancements. Integration of PID control with modern technologies such as embedded systems, artificial intelligence and Industry 4.0 platforms is also discussed.
Keywords: PID Control, Industrial Automation, Feedback Systems, Process Control, Mechatronics
