摘　　要：简要介绍当今异步电动机直接转矩控制研究的热点难点 ,分析了现场可编程逻辑器件 (PFGA)速度快、逻辑门数多的优势 ,实现了自适应无速度传感方案。并以高精度定子磁链圆为目标 ,提出了磁链圆闭环的方案。The paper introduces a DTC scheme based on FPGA (Field Programmable Gate Array). With the help of the high speed and mass logic gates features of developing FPGA, a sensorless control based on adaptive system is coming true. A flux close loop sheme is introduced, which based on a high precision flux round. The experiment result shows the advantage of FPGA in speed variable modulation area.
