摘要
对基于TMS320LF2407A的直流调速系统进行了深入的研究,设计的数字化直流调速系统主电路采用IGBT组成H型PWM变换器,以16位高性能DSP芯片TMS320LF2407A作为主控芯片实现数字控制,其特点是用DSP取代模拟触发器、电流调节器、速度调节器及逻辑切换等硬件,系统的电流调节器和转速调节器都用PI调节器,对系统进行了硬件及软件设计,在理论分析的基础上搭建了实验系统并进行了实验,给出了实验结果。
This digital DC speed control system is composed of DC motor and TMS320LF2407A, of which the DC motor is used as the controlled object and the TMS320LF2407A as controller. The system has the characteristics that the hardware devices, such as the analogous trigger, current regulator, rotation regulator and logic handoff, are replaced by single-chip computer. The hardware and software design are made, and the results are also given.
