Electromagnetic Levitation Device

Low-cost MagLev experimental platform able to perform semi-active control. This work proposes a discrete-time semi-active PID controller for the unstable magnetic levitation system. This platform consists of an Arduino micro-controller and a Rapsberry Pi computer. Both are low-cost devices with open-source software releases for communication and programming. Then, a modified PID controller with resetting actions is developed and implemented in the semi-active format.
