Performance Analysis of PI and PID Controllers in Process and Cruise Control Systems

Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) controllers are commonly employed in process and Cruise Control Systems (CCS) to control system behaviour. PID controllers have a derivative action to improve transient response and system stability, while PI controllers use proportional and integral actions to minimise steady-state errors. This study explores the performance of both controllers in these applications by designing and implementing them within each system. The methodology involves simulating the systems under different conditions, including variations in setpoints and disturbances, to observe how the controllers manage dynamic behavior. The study assesses both controllers' performance in various scenarios, emphasising their capacity to manage disruptions and preserve stability. The study's objective is to offer a thorough comprehension of the design and performance characteristics of PI and PID controllers in process and CCS, offering insights into their suitability based on specific system requirements and performance goals. The PI controller is found to be the best choice for certain applications due to its simplicity and effectiveness
