      <title>Direct Thrust Control by Direct Gap Flux Measurements for Linear Induction Motors</title>
      <link>https://trid.trb.org/View/795994</link>
      <description><![CDATA[In urban maglev system, linear induction motors (LSMs) provide propulsions. Because of edge effects, it is hard to obtain accurate observers for flux and thrust in direct thrust control system. To overcome the shortage, this paper has proposed a simple method to set coils to measure the gap flux directly since the gap is large enough to mount coils among surface of the primary core. Based on the measurements, a kind of direct thrust control has also been put up to enhance the propulsion. Simulations are showed in the end.]]></description>
