Firstly, development history and research actuality of modern AC speed regulation technique is introduces, basic theory of direct torque control recounted. Secondly, math model, electromagnetic torque model and flux linkage model of an motor in static two-phase coordinate of stator are recommended. Finally by using MATLAB/SIMULINK to establish a simulation model of asynchronous motor direct torque control system, has carried on the simulation results, the simulation results show that the direct torque control system can achieve good performance of speed adjustment.目录目录..................................................................................................................................................2第一章 绪论.....................................................................................................................................31.1 沟通电动机调速技术的进展和现状.................................................................................31.2 仿真工具 MATLAB/SIMULINK 介绍....................................................................................4第二章 沟通异步电机直接转矩控制调速系统分析与设计..........................................................52.1 沟通异步电机数学模型.....................................................................................................52.1.1 坐标变换.........................
