摘  要:
由于异步电机的数学模型是非线性强耦合的,在进行异步电机矢量控制的时候,参数的解耦成为矢量控制的关键,不同的解耦策略将直接影响到异步电机矢量控制的品质。提出通过坐标变换后,观测两相坐标系的电流,通过电压方程计算得到解耦电压,将控制电压引入解耦电压并相加,共同作用在电机上,发现转子磁链的变换对转矩、转速的变换影响很小,可知解耦效果良好。

摘  要:
Since the mathematical model of asynchronous motor is a nonlinear strong coupling,parameters decoupling is the key of vector control during asynchronous motor vector control. Different decoupling strategies directly affect the quality of asynchronous machine vector control. In this research,the electric current of two coordinate systems was observed through coordinate transformation. Decoupling voltage was calculated by voltage equations. Control voltage was introduced into decoupling voltage,and then they worked together on the motor. It was found that the torque of rotor flux and the speed transformation had little effects; but the decoupling effects were good.
