Abstract
The invention is an actively controlled radial magnetic bearing using inexpensive and rugged search coils as sensors instead of costly and delicate displacement or position sensors. It involves a feedback control scheme totally different from the conventional PID control algorithm. It comprises a velocity estimator with search coil signals as input, a velocity feedback controller with high-frequency gain and phase modification for the purpose of controlling flexible rotors, a self-starter automating the levitation, and a unique design and tuning method of analysis.
