| 摘 要： | 针对开关磁阻电机(SRM)的简化磁链法只能实现单相导通运行且导通区间固定的缺点,提出了一种结合固定关断角和自适应调节开通角的无位置传感器控制技术。利用曲线拟合关断位置磁链取代传统存储数据表,通过对比实时计算的动态磁链和曲线拟合的静态磁链,确定关断位置信号并估计转速和其他位置。考虑电机阻抗和电感的非线性特点,优化电感最小区域的开通角自调节模型确定导通区间。仿真结果验证了该方案的可行性和正确性,能够实现转子位置的间接检测,电机的运行效率得到进一步优化。

| Abstract: | In view of the fact that the simplified flux linkage method of switched reluctance motor (SRM) could only realize singlephase online operation and the conduction interval was fixed, a sensorless control technology combining fixed turnoff angle and adaptive adjustment of turnon angle was proposed. Using the curvefitting turnoff position flux to replace the traditional stored data table, the turnoff position signal and the estimated speed and other positions were determined by comparing the realtime calculated dynamic flux linkage and the curvefitted static flux linkage. Considering the nonlinear characteristics of the impedance and inductance of the motor, the conduction interval was determined by optimizing the selfregulating model of the opening angle in the minimum inductance region. The simulation results verified the feasibility and correctness of the scheme, which could realize the indirect detection of rotor position and further optimize the operation efficiency of the motor. |
