基于新型电机模型的异步电机矢量控制系统的研究

异步电机矢量控制中使用较多的电机模型为电压模型和电流模型两种。针对电压模型纯积分饱和、零点漂移;电流模型准确度受转子角速度影响过大等问题,提出一种新型的电机模型,有效的解决以上诸多问题,提高异步电机矢量控制精度。并利用matlab仿真软件在实验基础上对整个控制系统的工作原理进行介绍。

New Model Based on Vector Control System of Induction motor

Vector control used more motor model for voltage model and the current model of two kinds. Pure points for voltage model saturated, zero drift; The current model accuracy too much influence by the rotor angular such problems, the paper proposes a new kind of motor model, effectively solve the above problems, improve the control precision of vector control, and on the basis of experiment to the whole control system introduces the work principle.
