摘要: In recent years long stator linear synchronous motors (LLSM) started to replace the typical rotating converters like belts, chains, screw systems, pulleys, disks and so on. With LLSM a lot of drawbacks in machine concepts design can be prevented. For tracks, reducing reactive power individual control numerous moveable units, track is segmented several fed units. Because construction an operation with physical position encoder not desirable. that reason observers should used instead. this paper method multiple without proposed. The special behaviour during entrance exit one unit active segment described concept via master slave relationship Experimental results are presented demonstrate performance feasibility proposed method.
