Field Oriented Control is based on motor unification principle,energy conversion and vector coordinate transformation theory.It has many advantages such as novelty,practicability and advancement.By transforming coordinate,the stator current is decomposing two DC parts which orientated as the rotator magnetic field and controlled respectively.So magnetic flux and torque are decoupled.It controls the asynchronous motor as asynchronous way.
According to the AC Motor is difficult to the direct current motor in the velocity modulation,propose the AC Motor vector frequency conversion velocity modulation control strategy .The Paper introduced the baisc principle of vector control and designed Systems of AC Motor vector control and variable frequency speed regulationn.At the end, the system is simulated in SIMULINK and the result are shown.this thesis achieves the design and simulation about inductive motor's fully digitally vector control system.Using the motor model of vector in vertation in MATLAB and the system composed of these model,it realized the simulatiao.the result show that,choosing appropriste parameters,the system can archived rapid variable state response,high repellency and good variable and stabel state following ability. This type of system has better performance And SIMULINK.
