Automatic Code-generation of Cascaded Two H-bridge Inverter Based on Matlab

提出了一种基于实时代码生成工具(RTW)的TMS320F2812型DSP控制系统,给出了基于Matlab/RTW的系统设计方法和开发流程。结合此集成一体化控制平台,给出了一种基于嵌入式目标代码自动生成的2H桥级联5电平逆变器正弦脉宽调制(SPWM)波产生方法,利用Matlab/Simulink工具建立了算法模型、仿真验证算法后,给出了以定点DSP即TMS320F2812为目标的SPWM控制模型,并自动生成代码,编译、下载到目标DSP中运行,产生的波形与理论吻合。这种基于模型的设计流程,实现了工程开发过程中从算法设计到最终实现的所有阶段,提高了产品开发效率,降低了成本。

A control system of TMS320F2812 DSP is proposed which based on real-time workshop（RTW）.A system design method and development flowchart based on Matlab/RTW is introduced.An embedded code generation method is proposed in a cascaded two H-bridge inverter system.After building and validating the algorithm models in Matlab/ Simulink,a sinusoidal pulse width modulation（SPWM） control system model whose target board is TMS320F2812 DSP is presented.Automatic code-generation is accomplished from this model,then compiled and downloaded into the TMS320F2812 DSP.All the stages of development process are realized,and the development efficiency is increased and the cost is decreased.
