摘　　要：基于磁悬浮控制系统亟待一种体积更小、成本更低的位移传感器,研究了以电涡流传感器为原理的横向磁通传感器。基于该传感器的工作原理分析,采用粒子群算法设计了传感器的激励线圈与感应线圈参数,简化了横向磁通传感器的设计过程。所研制出的位移传感器灵敏度为7.2 V/mm,线性度为1.7%,可检测范围为±0.5 mm。将该传感器应用在一台磁悬浮永磁同步电机系统中,在电机转速20000 r/min时,高速磁悬浮转子仍保持稳定运行,且无论在稳态还是动态工况下,本文研制的横向磁通传感器均能满足磁悬浮电机位移检测和悬浮控制的要求,达到同类产品的控制效果。A displacement sensor with smaller volume and lower cost is needed for magnetic suspension control system.A transverse flux displacement sensor based on eddy current sensors is studied.The sensor analysis is based on its working principle.The parameters of excitation coil and induction coil are designed by particle swarm optimization,and the design process of the transverse flux sensor is simplified.The developed displacement sensor has a sensitivity of 7.2 V/mm,a linearity of 1.7%,and a detection range of±0.5 mm.The sensor is applied in a magnetic levitation permanent magnet synchronous motor system.When the motor speed is 20000 r/min,the high-speed magnetic levitation rotor still maintains stable operation.The transverse flux displacement sensors developed in this paper can meet the requirements of magnetic suspension motor displacement detection and suspension control,and achieve the control effect of similar products.
