Sensorless Vector Control of synchronous reluctance motors with disturbance torque observer
Industrial Electronics IEEE Transactions on, 2001Co-Authors: Tomonobu Senjyu, Takeshi Shingaki, Katsumi UezatoAbstract:The elimination of the position sensor has been one important requirement in Vector Control systems because the position sensor spoils the reliability and simplicity of drive systems. Therefore, we present a sensorless Vector Control technique for synchronous reluctance motors. The rotor position is calculated easily from ds-qs-axes flux linkages which are estimated with a first-order lag compensator. Furthermore, utilizing estimated rotor position as the input of the full-order observer, the rotor speed and disturbance torque are estimated. The proposed sensorless Vector Control scheme is demonstrated with experimental results

Research on the low speed performance of speed sensor-less Vector Control system
2015 IEEE 10th Conference on Industrial Electronics and Applications (ICIEA), 2015Co-Authors: Qiong Wu, Xing Qi, Guoli Li, Yuan FangAbstract:Compared with speed sensor Vector Control, traditional speed sensor-less Vector Control has many advantages, such as lower cost, higher reliability. But it also has many shortcomings at low speed, such as a lowly accurate speed, weak load capability. The above shortcomings partly block the large-scale application of speed sensor-less Vector Control. The fundamental reason is that most of traditional flux observation methods depend on the voltage model and EMF. In this paper, the traditional arithmetic of speed sensor-less Vector Control is improved. It abandons the voltage model to improve low speed performance, so it can be used in different working conditions.
