Abstract Linear Induction Motors LIM have excellent performance features such as high starting thrustforce alleviation of gear between motor and the moving parts reduction of mechanical losses of motiondevices high speed operation silence and so on Because of the above advantages the LIM has beenwidely used in industrial and transportation applications The driving principles of LIM are similar to thetraditional Rotary type Induction Motors RIM but its control characteristics are more complicated andthe motor parameters are time varying due to changes in operating conditions such as speed mover temperature and configuration of the rail In this research using feedback linearization sliding mode adaptive backstepping and neural networks speed position and flux tracking control of a LIM drive isstudied At first the controllers are proposed for the low speed LIM and the computer simulation resultsare shown Because of the structure of LIM and existence of considerable uncertainties in its parametersand complexity of the equations the controllers and the previous estimation methods can not guarantee aproper performance for the drive system at high speeds So considering the end effect robust slidingmode flux and speed controllers and secondary flux observer are proposed for the LIM drive Finally using adaptive backstepping controller and neural networks the speed and flux of the secondary considering the end effect are controlled
