摘要
直接转矩控制(D irect torque contro l)是一种新型的高性能的交流调速控制技术。本文介绍了异步电动机直接转矩控制的基本原理及TM S320F240 DSP芯片的主要特点和性能,给出了控制系统的设计方案和硬软件的实现方法。实验结果表明:该交流调速系统硬件电路简单、控制精度较高,具有良好的性能。
Direct torque control (DTC) is a new kind of high-performance AC timing control technique. This article introduces the main principle of asynchronous Motor DTC system as well as the main characteristic and performance of DSP chip TMS320F240. It shows the design project of DTC control system and the design method of T hardware and software. The experimentation results indicate that the AC system have these advantages such as good performance, simple hardware circuit and high control .
