| Abstract: | 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. |
