摘要
针对异步电机MRAS无速度传感器矢量控制系统,提出了将改进算法后的电压型转子磁链观测器作为MRAS的参考模型,从而消除纯积分环节初始相位和直流偏置的影响,提高了转速辨识的准确性。最后在Matlab/Simulink环境下,把改进后的MRAS转速和磁链观测器应用于该矢量控制系统,仿真结果证明了该算法的有效性。
In view of the asynchronous motor speed senseless vector control system of MRAS, the voltage rotor flux observer based on improved algorithm as reference model of MRAS, thereby eliminating the influence of initial phase and dc bias in pure integral link, then improve the accuracy of the speed identification. Finally by using Matlab/Simulink software, improving MRAS speed and flux observer is applied to the vector control system, the simulation results prove the effectiveness of the algorithm.
