碩士 === 國立臺灣科技大學 === 電機工程系 === 104 === This thesis proposed an implementation of a predictive speed controller for a sensorless synchronous reluctance motor drive system using high frequency injection method in stationary reference frame. A 25V, 1kHz high frequency signal is injected into the α-axis voltage. Then, by measuring the α-β axis high frequency currents, the rotor position of the SynRM can be estimated. The proposed control system is realized by a digital signal processor, TMS320F28335, and some hardware circuits. To verify the performance of the proposed system, several experimental results are shown. The experimental results can validate the theoretical analysis and show that the proposed drive system has good transient responses, load disturbance responses, and tracking performance. The proposed sensorless synchronous reluctance motor drive system can be applied for industry applications due to its simplicity.
