摘要
在分析了异步电动机数学模型的基础上,利用Matlab/Simulink构建了一个异步电动机直接转矩控制系统。通过Matlab仿真试验,得到电压、电流、转速、转矩及其磁链等的仿真波形。仿真结果证明,该控制方法具有较好的动态响应和较强的鲁棒性。
A direct torque control system of induction motor was constructed with Matlab/Simulink based on the mathematic module of induction motor. Through the experiment emulated by the Matlab, the waveform of stator voltage, stator current, rotor speed, electromagnetic torque and stator flux were given. The simulation results comfirmed this control method had higher dynamic response and comparatively stronger robustness.
