摘要:
三相异步感应电机矢量控制的关键在于磁场定向,而影响磁场定向的重要因素之一是电机参数转子电阻。为解决矢量控制动态性能对转子电阻的依赖问题,对三相异步感应电机转子电阻在线辨识技术进行了研究。建立感应电机数学模型,根据电机模型的数学表达式,提出了转子电阻的在线辨识方法,根据电机模型的等效电路图,推导了迭代求解转子电阻的数学表达式,在迭代求解过程中,以电机变量空间矢量图中的转子电阻电压和电流的平行关系作为判定计算结束的标志,得以准确求解转子电阻值。试验结果表明,该方法可有效地在线辨识转子电阻,计算简单,辨识精度高
Abstract:
The key of vector control of three-phase asynchronous induction motor is magnetic field orientation and one of the important factors affecting field orientation is the rotor resistance of motor parameters. In order to solve the problem that the dynamic performance of vector control depends on rotor resistance, the on-line identification technology of rotor resistance of three-phase asynchronous induction motor was studied. The mathematical model of induction motor was established. According to the mathematical expression of the motor model, an on-line identification method of rotor resistance was proposed. According to the equivalent circuit diagram of the motor model, the mathematical expression for solving the rotor resistance iteratively was derived. In the process of iteration, the parallel relationship between the voltage and current of the rotor resistance in the space vector diagram of the motor variable was used as the sign to judge the end of calculation. The rotor resistance could be calculated accurately. The experimental results showed that this method could effectively identify the rotor resistance on-line. It is simple to calculate and has high identification accuracy, which meets the needs of engineering applications.
