摘　　要：针对传统半导体激光器电源控制系统中,人工编写软件代码与硬件电路分开设计和测试,存在的开发周期冗长、代码不规范、关联性不强等问题,采用模型设计的方法替代传统人工软件编程。首先通过MATLAB/Simulink进行模型设计和系统仿真,使用DSP 28335作为控制芯片,分层设计环路控制建立离散闭环模型,然后对控制部分进行软硬件在环测试,搭建代码模型和配置参数,使用Simulink自动生成代码,编译后下载到DSP控制器。实验结果表明:使用模型设计可以极大地缩短半导体激光器电源控制系统的开发周期,避免了人工编写软件代码的不规范问题,加强了开发过程中软硬件的关联性,具有较高的工程应用价值。In the traditional semiconductor laser power control system,the software code is written manually and the hardware circuit is designed and tested separately,which causes the long development cycle,non-standard code,and weak correlation.This paper uses the method of model design to replace the traditional manual software programming.Firstly,model design and system simulation were carried out using MATLAB/Simulink.DSP 28335 was used as the control chip,and a layered loop control was designed to establish a discrete closed-loop model.Then,software and hardware in the loop testing was conducted on the control part to build a code model and configuration parameters.Simulink was used to automatically generate the code,which was compiled and downloaded to the DSP controller.The experimental results show that using the model design can greatly shorten the development cycle of the semiconductor laser power control system,avoid the non-standard problem of manual writing software code,strengthen the correlation between software and hardware in the development process,and has a high engineering application value.
