摘要
为提高异步电机控制系统的可靠性和适应性,在异步电机转子磁链定向的矢量控制系统中,对采用幅值补偿改进型积分器的电压模型进行了改进,增加了定子磁链积分正交性的闭环补偿自动调整磁链补偿量到最优值,提高了电压模型对定子磁链的计算精度。实验结果证明了该方法的有效性。
In order to improve the reliability and adaptability of control system for induction motors,a modified integrator which uses the error of orthogonal detection to adjust the stator flux compensation level automatically to an optimal value is presented.The precision of stator flux is improved by the modified voltage model.The experimental results show the good performance of the system.
