A speed and position detection method for high-speed maglev train driven by long-stator synchronous linear motor,based on measuring cog-slots of the long-stator,was presented.With this method,the principles,hardware structure and signal processing of an experimental system based on inductance sensor and DSP were elucidated in detail.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...
