| 摘 要： | 提出一种自抗扰磁链观测器,它对永磁同步电动机电感和永磁磁链的变化具有很好的鲁棒性.永磁同步电动机由电流调节逆变器来驱动,其中d-q轴电流是由两个前馈交叉耦合的比例积分控制器来解耦调节.电流调节器反映磁链偏差的积分项用来补偿由于电机工作温度变化等原因带来的电感和永磁磁链变化.实验结果表明了该观测器的有效性和优越性.

| Abstract: | A flux observer of active disturbance which is robust to the variation of inductance and permanent-magnet flux linkage was presented.Permanent magnet synchronous motor was driven by current-regulated inverter,where the d-q axis currents were controlled by two proportional and integral controllers of feedforward cross-coupling.The integral output of the current regulator reflecting flux errors were used to compensate variation of inductance and permanent-magnet flux linkage according to the operating tempera... |
