摘　　要：为了提升压滤机入料系统的实际运行效率,提出了一种将最大转矩电流比应用于直接转矩控制的效率优化方法。该方法根据实际电磁转矩的变化,在线动态地调节定子磁链的幅值,以获得单位电流幅值下的最大转矩输出效果。实验结果表明,该方法在相同的电磁转矩下仅需较小的定子电流即可实现全负载范围内的系统效率优化。In order to improve actual operation efficiency of feeding system of pressure filter,an efficiency optimization method with the maximum torque per ampere applied in direct torque control was proposed.The method adjusts amplitude of stator flux linkage dynamically based on actual changing of electromagnetic torque,so as to achieve the maximum torque output under unit current amplitude.The experimental results show that the method can realize efficiency optimization of the system in the whole load range with smaller stator current under the same electromagnetic torque.
