| 摘 要： | 提出了一种新的弱磁算法应用于感应电机的直接转矩控制。基本思想是根据给定转速值与实际机械转速的误差来调节磁通参考值,实现快速的弱磁控制。传统的弱磁控制算法需要计算基速,而提出的新算法不需要知道基速值,并且基本不依赖电机的参数。通过分析直接转矩控制不同时刻的最大转矩,推导出了新的弱磁算法的模型。对提出的算法进行了仿真,并与没有采用弱磁算法的传统的直接转矩控制进行了比较,通过仿真结果可以看出新算法的有效性。

| Abstract: | A new flux-weakening algorithm for direct torque control (DTC) of induction machine is proposed. The basic idea is to adjust the flux reference on the basis of the mechanical speed error,thus determining a spontanous flux weaking. The traditonal flux-weaking algorithm has to calculate the base speed. The new algorithm needn't know the base speed and it is basically independent of the machine parameters. A model of direct torque control of induction machine using the new algorithm is established according to... |
