Proportional –Integral – Derivative (PID) controllers have had great impact in the automobile manufacturing industry. It is a key component in the control of industrial robots used in automobile manufacturing plants. Automation of car manufacturing plant based on PID has greatly increased production, lowered cost, increased safety, quality and reliability. However the success of PID has improved the industrialization of more intelligent and advanced control strategies. This paper briefly discussed the basics of PID control, its impact in the car manufacturing plant and the challenges in the optimization of PID performance.
