title = "Research on dynamic characteristics of eddy current sensor for magnetic suspended flywheel",
abstract = "Aimed at the demand of the high precision displacement measurement in high speed magnetic suspended flywheel (MSRW), the variable frequency and amplitude modulation eddy current sensor is analyzed and the sensor's equivalent transfer function is given. A design method of phase-lead network for eddy current sensor lead compensation is proposed. The test result indicates that the sensor bandwidth can reach 10 kHz after phase compensation in high frequency band and the sensor's phase-lag is decreased markedly, the dynamic performance of the sensor is improved effectively. The MSFW experiment indicates that the sensor can supply precision displacement information of flywheel rotor and the MSFW can work at 40000 rpm stably after compensation.",
