摘　　要：针对永磁同步电机无位置传感器控制下的电感辨识问题,基于二阶滑模观测器位置辨识算法,分析了电机电感参数偏差对辨识反电动势和位置辨识偏差的影响。通过引入极值搜索(ESC)算法,补偿了位置辨识偏差中的稳态直流分量,实现了无位置传感器控制下电感参数的在线辨识和最大转矩电流比控制。最后通过仿真验证了本文理论分析的正确性和所提策略的有效性。Based on the position estimation algorithm of two order sliding mode observer, the influence of motor inductance deviation on back EMF and position identification deviation is analyzed. By introducing the extremum seeking algorithm(ESC), DC component in position identification deviation is compensated. At the same time, online identification of inductance and control of maximum torque per ampere without position sensor are realized. Finally, the correctness of the theoretical analys is and the effectiveness of the proposed strategy are verified by matlab/simulink simulation.
