Magnetic Lavitation Experiment
The aim of this lab is to model and control a laboratory-scale magnetic levitation system using analog controller. The objective is to keep a ferromagnetic object suspended, without contact, beneath an electromagnet. The electromagnetic force must be adjusted to counteract the weight of the object and account for disturbances. This is accomplished by measuring the location of the object using a non-contact sensor, and adjusting the current in the electromagnet based on this measurement in order to keep the object at a predetermined location. The system is inherently nonlinear and open-loop unstable. Negative feedback and phase-lead controllers are designed to stabilize this system. The controllers are designed using MATLAB and tested in Proteus software. Analog controllers are implemented using operational amplifiers, resistors and capacitors.
