摘要：提出了一种适合于基速范围的直接转矩控制系统仿真模型，引入了一些思路清晰、实现简单的新的建模方法。针对PI参数对系统的影响，改进了PI速度调节器的设计，改善了系统的磁链和转矩控制性能。同时给出了基于MATLAB/SIMULINK语言的系统仿真模型，仿真结果表明了该方法的正确性，能实现六边形磁链轨迹和近似圆形磁链轨迹的平滑转换，具有实用参考价值。

Abstract: A simulation model of direct torque control system for base|speed range was proposed, which introduces some novel modeling methods with clear idea and easy realization. The design of PI speed regulator is changed to improve the properties of the flux and torque of the system due to the affect of PI parameters to the system. Also the simulation model based on MATLAB/SIMULINK is given and some simulating results are presented to demonstrate this model is true and can realize the smooth translation between the flux track of hexagon and approximate circle, which has the advantage to refer in the study.
Key words: direct torque control; base|speed range; MATLAB/SIMULINK; simulation； PI regulator
