摘　　要：针对现有电子信息网络课程实验平台调速模块不完善的问题,研制了一套基于DSP系统的电子信息网络课程实验平台。实验平台采用TMS320F2812 DSP芯片作为核心控制系统,采用二相交-直-交变频器作为变频主电路,并基于SIMULINK设计DSP主程序,实现了电子信息网络课程平台的控制。测试结果表明,所设计的电子信息网络课程实验平台硬件部分满足设计需求,可实现硬件电路的SVPWM控制,并观测检测到各种波形;软件部分可通过改变所设计的速度调节器PI值、电流调节器PI值和转子回路时间常数Tr值,提高系统的稳定性和响应速度,进而实现对实验平台的控制,满足设计需求。Aiming at the imperfection of the existing electronic information network course experiment platform,a set of electronic information network course experiment platform based on DSP system is developed.The experimental platform adopts the TMS320F2812 DSP chip as the core control system,adopts the two-cross-direct-cross frequency converter as the main frequency conversion circuit,and designs the DSP main program based on SIMULINK to realize the control of the electronic information network course platform.The test results show that the hardware part of the experimental platform meets the design requirements,can realize the SVPWM control of the hardware circuit,and observe and detect various waveforms;the software part can improve the stability and response speed of the system by changing the designed speed regulator PI,so as to realize the control of the experimental platform and meet the design requirements.
