摘要
直接转矩控制是继矢量控制之后又一高性能交流调速新方法,它基于定子磁链定向,数学模型简单,具有输入电压波动时控制的鲁棒性、控制对象参数变化的低敏感性、完全的转矩瞬态控制等控制特性。本文以TMS320F2407为核心构成控制器,对小功率异步电机直接转矩控制的实现进行了初步探讨。
Direct torque control （DTC） is a new method for asynchronous motor speed regulating after the vector control. It is based on stator static axis, which has a simple mathematic model and realizes some high level of performances, such as robustness to undulation of input voltage, low sensitivity to parameters change. In this paper,Base on the mainstream DSP processor--TMS320LF2407 , the new method of DTC based on speed sensor less for AC motor is present.
