直接转矩控制技术是目前最为优良的交流电机控制技术,数字信号处理器(DSP)的高速运算和实时处理功能为直接转矩控制技术的数字化提供了基础。本文介绍了直接转矩控制的基本原理及TMS320LF2407 DSP的特点,给出了以TMS320LF2407 DSP为核心的异步电动机直接转矩控制系统的设计方案及软硬件的实现,同时对直接转矩控制系统进行了实验和仿真,验证了直接转矩控制技术的优良性能。

Direct torque control is the most excellent control technology for induction-motor at present. Digital signal processor with high speed arithmetic and logic operation are the base for its digital realization. In this paper, it introduces the principle of direct torque control and the character of TMS320LF2407 digital signal processor. At the same time, it gives the software and hardware design of direct torque control system for asynchronous-motor based on the TMS320LF2407 DSP. With experimentation and simulation, it proves the good character of direct torque control.
