【摘要】 传统的恒压频比控制存在稳态精度低、低频输出转矩小等缺点。提出了一种带有转差角频率补偿和定子电阻压降补偿的异步电机标量控制方案。仿真和实验结果验证了本方案的具有稳态精度高、低频输出转矩高等优点。更多还原

【Abstract】 The traditional VVVF control schemes have the disadvantage of poor steady precision and the small output torque working in the low frequency ln this paper the scalar control scheme with the slip frequency compensation and the stator voltage dropping compensation is proposed,simulation and experiments validate the proposed scheme has good steady precision and high output torque.更多还原
