Couple compensation of magnetic forces of transverse flux linear induction motor

The magnetic force across the air-gap between primary and secondary in linear induction motor is for the most part constrained by bearing or linear guide. But, the existence of normal or levitation force gives us a possibility to drive the linear motor stably without the bearing. However, as the normal force depends inevitably and strongly on the thrust force, it is essential to decouple both forces for two control inputs. Therefore, to control the thrust force and the normal force on the secondary part of linear induction motor independently, the various methodologies have been presented. In this paper, we suggest a novel approach capable of compensating the couple between both forces and another input besides their corresponding inputs for the transverse flux linear induction motor.
