The single-sided linear induction motor has been used widely in low-speed maglev trains. In this paper, an H∞ control strategy under field orientation has been proposed to reduce the end effects and enhance the dynamic performance of the control system. First, the mathematic model of the SLIM is established. Then, the model is simplified, the end effects are attributed to the uncertainty of the system and the design is turned into an H∞ mixed-sensitivity optimal design. After that, an H∞ method based on internal model principle is proposed, by which a speed controller is designed finally. Simulation results indicate that a system with an H∞ controller has much better performance than that with a traditional PI controller.
