Enhanced Linear ADRC自抗扰算法.pdf

ADRC自抗扰滤波算法High-frequency (HF) signal injection methods have been widely employed in the sensorless control of interior permanent magnet synchronous motor (IPMSM) drives from zero to low speed. However, the control performance will be deteriorated severely when the motor subjects to the disturbance. To cope with this issue, an enhanced linear active disturbance rejection control (LADRC) based HF pulse voltage signal injection method is proposed in this paper
