摘  要：在全阶磁链观测器中加入反馈矩阵可以解决平滑切换及阻尼的改善问题，引入增益矩阵可以提高响应速率。在模型参考自适应方法的基础上建立全阶磁链观测器观测模型，把设定的电机转速作为参考模型，与磁链观测后的计算速度作比较，通过不断修改参数值使电机运行趋于稳定。在Matlab中的Simulingk仿真模块中建立控制电路模型，得到加入增益前后的磁链观测图和速度推算图，通过比较图像验证增益矩阵的改善作用。

Abstract:  Feedback matrix in the full order flux observer can resolve the problem of smooth switch and damping improvement, the introduction of the gain matrix can improve the response rate. Established the full order flux observer model on the basis of the model reference adaptive control, set the motor speed as a reference model,compared with the speed calculation through the flux observer, made the motor running stabilized tend to continuously modify the parameter values. Set up the control circuit model in the the simulation module of Matlab/Simulink, got the image of speed and the flux observer before and after adding the gain,then proved the improving function of of gain matrix by comparing the image.
