This paper emphasises on the control of a magnetic ball levitation system using an enhanced proportional integral derivative (PID) controller. Though PID controllers produce a controlled output for stable and unstable systems, the performance of the system in terms of overshoot, settling time, Integral Square Error (ISE) and Integral Absolute Error (IAE) are poor. To solve this problem, an enhanced PID controller is designed based on the system open loop transfer function. A compensator in cascade with the PID controller is designed based on bode plot response of the system. The efficacy of the proposed controller is demonstrated via simulation study of a magnetic ball levitation system. The results are compared with the classical PID controller. The proposed controller eliminates the overshoot and reduces ISE and IAE, thus provides smoother system responses.
