摘要
考虑到传统直接矢量控制运算量庞大且极易产生饱和漂移和累积误差,经过对转子磁链的分解与近似,研究了一种基于简化模型的感应电机矢量控制方法。该方法通过直接对励磁电流分量和转矩电流分量进行闭环控制,将复杂的电流转电压过程归入PI调节器,简化了感应电机直接矢量控制。实验结果表明,该方法动态抗扰动指标可靠有效,系统编程量少且不易产生饱和振荡。
On account of the heavy computations,easy saturation and cumulate errors of conventional direct vector control, the vector control of induction motor hased on simple model is studied.The detailed scheme is described based on the rotor flux which is decomposed and approximated.Through the direct close loop control of magnetization current and torque cur- rent,file complex transformation process of current to voltage is included by PI regulator,and the direct vector control of induction motor is simplified.The proposed method is effective experimental verification.lt shows that the simplicity of the code program, rare saturation and shock.
