摘要
在异步电机数学模型的基础上,利用Matlab/Simulink软件构建异步电动机直接转矩控制调速系统。对仿真模型中的定子磁链观测器模块进行描述,并简要说明空间电压矢量对磁链和转矩的作用及影响。通过对异步电机进行仿真实验,得到电压、电流、转速、转矩以及磁链的仿真波形。
A direct torque control (DTC) system of induction motor is constructed with Matlab/Simulink based on the mathematic module of induction motors.The mod- ule for stator flux observation is illustrated.And the paper explains how the space voltage vector affects the motor’s stator flux and electromagnetic torque.At last an experi- ment with definite parameters is emulated and the wave- form of stator voltage,stator current,rotor speed and elec- tromagnetic torque are given.
