| 摘 要： | 测速定位系统是高速磁浮列车牵引和运行控制基础,与轮轨列车的系统相比,存在着如悬浮间隙波动、长定子轨道接缝及非接触式绝对位置读码等可能影响系统正常运行的特殊问题.为了降低悬浮波动对相对位置检测的影响,提出了利用悬浮间隙归一化处理相对位置检测信号的方法,使输出统一变换为8mm悬浮间隙下的信号,达到了磁极相角精度2.8°的检...

| Abstract: | Speed and position detection system is the basis of propulsion and traction control for high speed maglev train.Compared with traditional railways,high speed maglev trains have some exclusive problems which can affect system proper working,such as levitating fluctuation,joint gap of long stator track and contactless reader for absolute position.To reduce detection error of relative position due to levitating fluctuation,a method utilizing levitation gap to normalize detection output into the one of 8mm levi... |
