异步电动机低速及弱磁环节直接转矩控制系统的建模和实现

Modelling and simulation for DTC system of asynchronous induction motor with MATLAB/SIMULINK in low-speed and weaken flux range

在简单介绍电力牵引系统直接转矩控制低速和弱磁环节控制理论的基础上,用MALTAB/SIMULINK对这两种方法进行建模和仿真,并给出仿真结果。

Based on simple principle introduction for electrical traction system of Direct Torque Control in low-speed and weaken flux range,this paper sets up a simulation module for these two methods and gives out simula tion re-sult.
