摘　　要：在DC-AC变换器的控制系统中,传统使用数字信号处理(DSP)作为控制器开发控制系统存在时间周期长、编程难度高等问题。为解决该问题,采用将Matlab/Simulink和Code ComposerStudio(CCS)结合使用的方法快速生成代码。选用单相全桥DC-AC逆变电路作为研究对象,通过Simulink仿真并生成正弦脉宽调制(SPWM)控制信号代码,在Matlab和CCS之间建立关联,并将生成的代码运行到以TMS320F28335为核心的主控板,进而生成SPWM控制主电路的逆变器。通过基于模型设计(MBD),验证了可以通过Matlab/Simulink仿真实现DSP自动生成代码,并应用于DC-AC逆变器,同时该方法具有很高的准确性和可行性。In the control system of the DC-AC converter,the traditional digital signal processing(DSP)used as the controller to develop the control system suffers from long time periods and complex programming.In order to solve this problem,a method of combining Matlab/Simulink and Code Composer Studio(CCS)is used to quickly generate code.The single-phase full-bridge DC-AC inverter circuit is selected as the research object.The sinusoidal pulse width modulation(SPWM)control signal code is generated through Simulink simulation,and the association between Matlab and CCS is established.The generated code is run to the main control board which has core TMS320F28335.Then the SPWM is generated to control the inverter of the main circuit.The model-based design(MBD)shows that the code can be automatically generated by DSP through Matlab/Simulink simulation and applied to DC-AC inverter.At the same time,this method has high accuracy and feasibility.
