摘　　要：通过研究异步电机直接转矩控制原理,给出了用TMS320F240实现异步电机直接转矩控制系统的硬件框图。实验结果表明系统能实现电机快速动态响应,具有一定的实用价值。This paper proposes a direct torque control （DTC） system of asynchronous AC machine based on digital signal processor （DSP） TMS320F240. Through the research on direct torque control theory of asynchronous AC machine, this paper introduces the designs of the system hardware structure. At last, an experiment for this system is also produced. The experiment results show the system can realize the character of rapid dynamic response and have some practical values in the AC modulating speed.
