【Abstract】 The influence of nonlinear magnetic circuit on stator flux is analyzed in this paper, and stator flux oriented control is employed to minimize the direct dependence of control system on motor parameters. Furthermore, the paper presents a stator flux oriented slip control scheme based on the dynamic motor model. The performance of the system can be improved effectively by controlling the differential of the stator flux amplitude and the torque component of stator current via d axis voltage and slip respectively.更多还原
