摘　　要：在常规电机参数辨识中需要额外设备和电机堵转,实际应用不方便。提出了一种基于矢量控制的电机参数离线辨识方法,该方法通过设定励磁电流、转矩电流和磁链角对电机参数进行辨识。实验结果表明,该方法能够减小由死区、三相电阻不对称等因素造成的辨识误差,辨识结果应用到矢量控制系统中,实现快速响应和稳态误差保持在1%之内。It is not convenient in actual cases for conventional method of motor parameter identification that requires additional equipment and man-made motor locking. In this paper, an off-line parameter identification strategy based on vector control for induction motor was given, which achieved by setting excitation current, torque current and flux Angle. The experimental results show that the method can effectively reduce identification error that generated by dead zone, asym- metric of three-phase resistor, etc. And the identification result was applied to the vector control system, achieving rapid response and steady-state error within 1%.
