基于dSPACE1005标准板的感应电机矢量控制

Vector Control for Induction Motor Based on d SPACE1005 Standard Board

感应电机矢量控制通过坐标变换将静止坐标系下的三相交变定子电流转变为同步旋转坐标系下的两相直流,再利用转子磁场定向进行解耦,对定子电流的励磁分量isd和转矩分量isq进行独立控制,使得感应电机的控制能像直流电机那样高效。论文中采用的d SPACE半实物仿真系统实现了与MATLAB/Simulink的完全无缝连接,搭建模块就能生成代码并加载到实时硬件中运行,减少人工输入大量的代码,方便控制算法的验证。

Induction motor vector control transforms three phase stator current under the static coordinate system into DC under synchronous rotating coordinates through coordinate transformation, and control excitation current and torque respectively by using field orientation. It realized the independent decoupling for excitation current isd and torque isq, SO as to achieve the goal that made induction motor have high performance of speed control like DC motor. In this paper, dSPACE system is seamlessly connected to the MATLAB/Simulink building module can generate code and loaded into the real-time running in hardware, reduce a lof of mannual input code, convenient for control algovithm.
