摘　　要：此处探讨了一种基于d轴电流直接求解的定子磁场定向异步电机的控制策略。首先对定子磁场定向矢量控制的基本原理进行了介绍,在此基础上,推导了d轴电流直接求解公式,并建立了控制系统的数学模型。给出一种混合模型定子磁链观测器的设计方案,并通过Maltab/Simulink进行了仿真,在以TMS320F2812为控制器的小功率实验平台进行了实验,结果证明了此处所述控制算法的有效性和可行性。This paper discusses the asynchronous motor control strategy of the stator flux-oriented based on direct measurement of d current.A fundamental principle of vector ＂control based on the stator flux-oriented is introduced.On the basis of this, the formula of calculating d current directly is derived and the math model of control system is built.Some stator flux observers is analyzed and the scheme based on hybrid-flux observation is shown.Finally, validity and feasibility of control method of asynchronous motor based on the stator flux oriented are verified by Matlab/ Simulink software simulation and low-power experimental platform experiment.
