Research on current decouple control based on stator-field orientation vector control

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.
