摘　　要：从分析变频调速原理和电动机的统一理论出发,基于三相数学坐标的变换建立三相异步电机动态数学模型.通过分析此动态数学模型,在Matlab/Simulink环境下构建了这种矢量控制系统的仿真模型并进行了深入仿真研究.仿真结果表明通过调节各个模块的参数,可得到理想的仿真波形,实现整个系统的仿真,从而验证了仿真系统模型及所建立的调速系统动态数学模型的正确性.Based on the principle of frequency control of motor speed, and motor unified theory, the dyamic mathematical model of three phase asynchronous motor is established under three-phase coordinate transformation. To analyse this dynamic mathematical model, a simulation model is established under Matlab/Simulink and simulation studies are performed to verify the feasibility of the proposed vector conrolled drive. The results not only indicate the validity of the dynamic mathematical model and simulation model, but also show that by adjusting simulation parameters in each model, perfect simulation waveform is obtained.
