Synchronous Reluctance Motor (SynRM) has drawn worldwide attention due to its low production cost and no magnetic material. This thesis aims at the sensorless control using high-frequency injection method combined with adaptive backstepping controller. As a result, the system is robust, and the adaptive backstepping controller provides better responses. Also, the principle of SynRM and field-oriented control are discussed. The proposed control system is realized by a digital signal processor and some hardware circuits. To verify the performance of the proposed system, several experimental results are shown. The results can validate the theoretical analysis and show the proposed system having good transient responses, load responses, and tracking responses.
