Abstract Permanent Magnet Linear Synchronous Motor drives have excellent performancefeatures such as no backlash and less friction high speed and high precision in longdistance location in addition it has simple mechanical structure which is resulted inhigher reliability and frame stiffness and high thrust Because of these advantages thePMLSM drive has been used widely in industry machine tools and robotics andtransportation applications The driving principles of PMLSM are similar to thetraditional Rotary type Permanent Magnet Synchronous Motors RPMSM but itscontrol characteristics are more complicated that is because of the motor parametersare time varying due to changes in operating conditions such as speed mover temperature and configuration of the rail In this research using feedback linearization adaptive backstepping method and Artificial Neural Network ANN the speed position and flux tracking control of this drive is studied At first the controllers areproposed when the armature slides in the magnet array region and the computersimulation results are shown Because of complex structure of PMLSM and in additiondue to existence of considerable uncertainties that exist in its parameters thecontrollers can not guarantee a proper performance for the drive system when thearmature goes out from the PM array So considering the operation motor in theextended region the sliding mode flux and speed controllers are proposed for the LIMdrive Finally using adaptive backstepping controller and neural networks the positionand flux of the motor considering the extended region are controlled
