摘　　要：针对传统DSP代码编程繁琐、程序修改复杂、效率低等缺点,研究一种基于模型的编程方法。该方法结合Simulink中的Embedded Target for TI C2000DSP模块对算法进行搭建,然后利用Real-Time Workshop完成代码自动生成并下载到DSP中,具有编程简单、容易对算法进行修改、效率高等优点。以TMS320F2812DSP作为控制器,将这种方法应用于异步电机的直接转矩控制DTC系统的设计,实验中电机能够平稳运行并拥有良好的起动、制动性能,结果表明这种方法具有可行性和高效性的特点。One programming method based on model was researched in allusion to that traditional DSP had defects,such as complicated programming of code,complicated modification of program,low efficiency,etc.,generated codes automatically by using Real-Time Workshop and downloaded them to the DSP after building up the algorithm by combining Embedded Target for TI C2000 DSP module in Simulink,with advantages,such as simple programming,easy modification to algorithm,high efficiency,etc.The motor in the experiment could run stably and had excellent starting and braking performances when the method was applied to the design of direct torque control DTC system of the asynchronous motor by taking TMS320F2812 DSP as the controller,and during the application,the feasibility and high efficiency of the method were verified.
