| 摘 要： | 参考磁场定向控制(FOC)、直接转矩控制(DTC)两种方法的特点,提出了一种矢量转矩控制(VTC)的方法,它解决了传统DTC的输出电压矢量与控制变化量之间没有定量关系的缺陷,建立了输出电压矢量与控制变化之间的函数关系,同时改进了磁链低速模型.实验结果表明,该方法能够有效改善电机的输出特性.

| Abstract: | The paper proposes a novel strategy for torque control, namely vector torque control (VTC), taking into consideration the field orient control (FOC) and direct torque control (DTC). It sets up a function to resolve the problem that no definite relation exists between output vector and control variations in the conventional DTC. Also it improves the stator flux model at low speed. In the end, experimental results show that the proposed strategy can improve the output characteristics of induction motor. |
