摘要
本文就定子电压定向矢量控制方法的原理和实现策略进行了讨论 ,提出了一些改进措施 ,并在此基础上给出仿真及实验波形。结果表明 ,该方法不仅可获得磁通和转矩的解耦控制 ,并且比传统的矢量控制方法 ,还具有减少坐标变换的环节、在动态过程中能保持定转子磁通恒定、受转子参数变化的影响很小等优点 ,能够简单地实现高精度。
The theory and realization method of Voltage Oriented Control (VOC) system for Induction Motor is discussed and some improvements are proposed in this paper A simple but high-accuracy and high-performance dynamic speed control scheme is presented then The simulation and experimental results indicate that this system not only decouples the control of flux and torque,but also has many advantages as compared to traditional vector control systems, such as avoiding the complex coordinate transformtaion, keeping the stator and rotor flux constant in transient state as well as in steady state, being robust to rotor parameters, etc
