Analog Control Systems: Levitation in Education

Created using ChatSlide

This educational project explores the creation of an analog closed-loop system aimed at levitating a neodymium magnet through real-time feedback. Utilizing components such as a hand-wound electromagnet, a SS49E Hall sensor, and an LM358 op-amp, the project demonstrates fundamental challenges like Earnshaw's Theorem and static levitation instability. Despite achieving momentary levitation, the system faces oscillation issues, prompting improvements like derivative control and component...
