Closed-loop electromagnetic forces calculations and controls of a noncontacting industrial steel plate conveyance system

An online electromagnetic force calculation scheme, along with the appropriate closed-loop control design for driving a linear induction machine prototype, will be developed for practical industrial steel-plate conveyance system applications. Through appropriate signal detections and feedback controls, real-time balanced normal and propulsive forces can be stably generated onto the motor secondary mover (steel plate), and the objectives of noncontacting conveyance system designs and constructions can be successfully achieved.
