摘　　要：因感应电机矢量控制中对电机参数的准确测量之需,提出一种工业应用的参数辨识方法。该算法的基础是基于分类的矢量控制,对逆变器的输出矢量进行分类可以将算法线性化以节约处理器的计算时间,并且验证了其谐波含量也更低。电机工作时转矩和磁链对电阻的变化敏感,而传统的辨识模型对电机参数有一定依赖性,稳定性差。鉴于此,在分类法矢量控制的基础上设计了基于无功功率的模型参考的自适应系统以辨识转子电阻。因无功功率模型中不含有受电机运行工况影响的参数,保证了算法的鲁棒性。经仿真和实验分析,验证了所设计的辨识系统的灵敏性、准确性和可靠性。In order to accurately measure parameters of the induction motor in vector control,the paper presented an parameter identification method which is easy for industrial application. Based on the classification algorithm used in vector control, the output of the inverter is classified to realize vector linearization and save computing time.Furthermore,its harmonic content is lower than the traditional methods. Because the motor torque and flux variations are sensitive to resistors,the traditional model of the motor parameter identification has some dependency,such as poor stability. Based on classification of vector control,an adaptive system is designed by using the model of reactive power to the rotor resistance identification. Because reactive power model parameters under operating conditions are not affected,it ensures the robustness of the algorithm. The simulation and experimental analysis verify the sensitivity,accuracy and reliability of the system designed.
