Abstract:	This paper proposes multiloop PID control for a field-sensed magnetic suspension system. The magnet position is measured by the magnetic field sensor and the coil current is driven by PWM technology. Two control loops are implemented. The inner loop is PI control and the outer loop is PD control. This control scheme is mathematically analyzed by the Routh stability criterion. The stability of the magnetic suspension system is guaranteed and the experimental result is accomplished successfully. This paper is technology-education-oriented. The proposed magnetic suspension system is low-cost and appropriate for hands-on experiment by undergraduate control education students. The video of these experiments has been uploaded to YouTube, where it can serve as teaching material for undergraduate control curricula.
