S-Function在TMS320F2812的SVPWM算法仿真

S-Function Study in Application of SVPWM Algorithm Simulation Based on TMS320F2812

S-Function有两种形式,一种是M文件,另一种是C-MEX文件,前者支持功能强大的工具箱,后者支持C、C++等语言,并且在仿真上更快速有效。基于TMS320C2812的SVPWM算法在TI的CCS软件中实现,并且支持C、C++语言,这给程序通过S-Function移植到MATLAB中进行仿真提供了一种有效途径。利用在Simulink中搭建的三相全桥逆变器模型与S-Function编写的算法模块相结合,并进行仿真,简单有效地说明了S-Function的实际应用并验证了SVPWM算法的正确性。

S-Function has two forms： the M file and the C-MEX file. the former supports a powerful toolbox, the latter supports C, C＋ ＋ and other languages is more quick and efficient on simulation. The SVPWM algorithm based on TMS320C2812 is implemented in TI＇s CCS software which supports C, C＋ ＋ language, providing an effective way to the algorithm ported to MATLAB for simulation through S-Function. Combining the three-phase inverter system module built by simulink and the control algorithm written by S-Function for simulation explains the practical application of S-Function and proves the correctness of the control algorithm.
