Adaptive speed control for linear induction motors considering end effect

In this paper, the speed control problem of linear induction motors is considered based on a semi-current-fed model. Once deriving the mathematical model considering end effects, adaptive control design is developed by using so-called virtual desired variable synthesis. Based on the synthesis method, the control law is naturally deduced while thrust load and mechanical parameters are unknown. Finally, practical experiments for linear induction motors are carried out to verify the theoretical derivations.
