MMC topology rectifier control system design based on new type C MEX func- . j tion. Computer Engineering and Applications, 2018, 54 （4 ）：225-230. 机 a 算 e Abstract ：The common C MEX function is confined to calculate child module, it is not used to design the overall control c . scheme. The coder is not compatible with the DSP chip software, and can ’t be done transplantation and experiments. This 计 w paper proposes a new multiple file structure C MEX function. The main function, child module and header file are inte- grated to the multiple file structure. The child module is called by the main function to calculate the whole simulation pro- w gram. The C MEX code is designed based on the modular multilevel topology rectifier current vector control algorithm. It w uses fixed-point DSP model, which can realize efficient transplantation. The simulation results show that the C MEX func- tion realizes the current decoupling and has the characteristics of high integration and efficiency. Key words ：multilevel topology; multiple file structure; vector control; fixed-point 摘 要：常见的C MEX 函数局限于对控制系统局部子函数的C 代码验证，不能实现整体方案设计；并且与DSP 芯片 的软件语法不兼容，无法进行代码移植与实验。提出一种新型多文件结构的C MEX 函数，将主函数、
