摘要
介绍了交流电机变频调速直接转矩控制原理,提出了以TMS320F2812为核心的控制系统软、硬电路设计方案,充分利用芯片片上外设丰富、运算速度快的特点,简化了系统的硬件设计,给出了用DSP实现直接转矩控制的主程序和中断程序流程图。实验表明:TMS320F2812的高速性能使系统控制的实时性和精确性得到了很大的提高,动、静态性能得到明显改善。
Introduced principle of variable frequency and speed with DTC, presented design method of the control system＇s software and bantware circuit with TMS320F2812. The method utilized completely the wealthy peripherals and high speed calculation function of chip, simplified hardware design,block diagram of main program and interrupt program were given for DTC control with DSP.The experiment results show that the real-lime character and accuracy of the control system was improved, the dynamic and static performance was remarkably improved too.
