摘要
采用SVPWM的方法对电压型逆变器的6个基本电压矢量进行线性组合,得到6个合成电压矢量。在此基础上,优化设计出一种三相异步电动机直接转矩控制系统。在MATLAB/SIMULINK环境下建立该系统的仿真模型,仿真结果表明,系统的磁链、转矩脉动小,电流谐波小,具有良好的动态性能和稳态性能。
The 6 basal voltage vectors of voltage source inverter were combined linearly through space vector pulse width modulation, the 6 complex voltage vectors were gained. A novel 3 - phase asynchronous motor direct torque control system was designed on the foundation. The system simulation model in MATLAB/SIMULINK were made and the simulation results showed the advantage of the system which had small flux linkage and torque ripple, small stator harmonic current, well transient response and steady response.
