摘　　要：异步电动机的软起动可控制电动机的起动电压和电流,减少电动机起动过程对电网和负载的冲击,同时保证电动机运行平稳。利用MATLAB软件中的动态仿真工具Simulink对采用PI电流闭环控制的异步电动机软起动系统建模并进行了实例仿真。仿真结果和实验结果吻合较好,证明仿真方法是正确、有效的。By using soft starting, the starting voltage and starting current of asynchronous motor can be controlled, the impact on electric power system and load during the startup can be reduced, and also enables asynchronous motor to rotate steadily. The simulation model of soft starting system by using PI current closed loop control for asynchronous motor was established based on MATLAB/Simulink and simulation was carded out through actual example. The simulation results were close to the experimental ones, which verified the correctness and validity of the simulation method.
