| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 88 === The objective of this thesis is to realize sensorless vector-controlled drives for permanent magnet synchronous motor (PMSM). The system consists of a PC-based control board and software developed using Simulink. In comparisons with other approaches only current sensors are required for the implementation of sensorless vector-controlled PMSM drives. Neither shaft sensor nor voltage sensor is required. The synchronous speed of motor is estimated using the feedback current signals and voltage command.
It will be demonstrated in this thesis that the implemented sensorless PMSM motor drives provide moderate speed response and can be applied to the particular applications not requiring going through very low speed range, e.g. fan.
Experimental results derived from a PC-based test system will be presented to confirm the above-mentioned claims.
