Nonlinear adaptive backstepping motion control of linear induction motor

In this paper, we propose a nonlinear adaptive controller and an adaptive backstepping controller for linear induction motors (LIMs) to achieve speed/position tracking. A nonlinear transformation is proposed to facilitate controller design. Besides, the unique end effect of the LIM is also considered and is well taken care of in our controller design. Stability analysis based on Lyapunov theory is also performed to guarantee that the controller design is stable. Also, computer simulations and experiments are undertaken to demonstrate the performance of our controller designs.
