摘　　要：研究了以定子磁场定向的矢量控制.推导出了以定子磁场定向时异步电动机的数学模型.在此基础上,导出了定子电流在同步旋转坐标轴上的两个分量与磁链之间的关系和瞬时转矩公式,而且针对定子电流在q、d轴分量之间的解耦也做了进一步的探讨,数学模型的建立及其仿真结果表明,可以实现电流isq只控制转矩Te,电流isd使Ψ1恒定的解耦控制.Based on vector control of stator-field orientation,the paper induces mathematical model of stator-field orientation for asynchronous motors.The paper also induces the relationship between components of stator current and magnetic link in a synchronous rotating coordinate system.In addition,this paper carries out a further discussion on the coupling of the components of the stator current on axis q and d.Establishing the mathematical model and its simulation results indicate that current isqonly control torque and current i_(sd)control Ψ\-1,and decouple control can be realized.
