摘要
针对长定子直线同步电机驱动的高速磁浮列车,提出了采用特定的立体探头线圈来减弱定子轨道齿槽结构的影响,同时,抑制外界磁场干扰,以实现准确测量悬浮气隙。阐述了基于电感式传感器和现场可编程门阵列(FPGA)信号处理的悬浮间隙测量系统的硬件结构、工作原理及其信号处理方法。试验证明:该设计是可行的,能够满足高速磁浮列车控制系统的要求。
A method of gap determination for high-speed maglev train driven by long-stator synchronous linear motor, based on tridimensional coil ,is presented. In which method, reliable gap determination is given with lesser effect of tooth-groove and electronmagnetic interference. With this method, the principles, hardware structure and signal processing of an experimental system based on inductance sensor and FPGA are elucidated. Experiment shows that the system has the features of hard real time and high measuring precision, which meets the requirement of the operating control system of high-speed maglev train.
