| Abstract: | In order to overcome the uncertainty of floated gyroscope in the dynamic condition, and upgrade me dynamic performance and stability of gyroscope, a control system of digital active magnetic suspension was designed. In the system, a method of digital demodulation based on phase coherence was used to calculate the feedback data, then the float of floated gyroscope was positioned in the center precisely and quickly. Testing results show that the design is feasible, and 24 h random drift of floated gyroscope with active magnetic suspension is 0.000 6° /h. |
