Magnetic Levitation System Prototype Using Proportional-Integral-Derivative Control

Abstract Magnetic levitation is a phenomenon of objects by using magnetic field to defy gravity. an interesting research topic widely used in industry or transportation such as trains, conveyors, lifts, and many more. In general, can be realized regulating the current source. However, due normally unstable power supply source, results instability. Therefore, control system needed stabilize system. this study, lifting has been developed Proportional-Integral-Derivative (PID) method hall effect sensor. The result shows that PID controller, object successfully floated stably at reference point form 1.4 cm 6.5 with error ± 0.02 overshoot 0.2 cm, if without PID, oscillations occur rate 0.1 0.6 cm.
