| Abstract: | By using soft starting,the starting voltage and starting current of asynchronous motor can be controlled,the impact to electric power system and load during the startup can be reduced,and also enables asynchronous motor to rotate steadily.The work state of soft starting was analyzed and mathematic model was set up.Soft starting system by using PI current closed loop control for asynchronous motor was programmed based on MATLAB and simulation was carried out through actual example.The simulation results were analyzed. |
