说明：  异步电机作为电网中较为主要的负荷，对其的控制一直是重要问题。在异步电机的起动过程中，若直接起动，则会引起较大的电流，会影响电网的稳定和安全；且起动转矩和运行效率也较低。为改善上述问题，使用软起动器对异步电机进行起动，可实现启动电压的无极调节，从而限制启动电流，可在一定程度上改善电机性能。本文采用电流闭环作为控制方式，并采用MATLAB对异步电机软起动系统进行模型搭建和仿真，进而说明了软起动的优势。(As the main load in the power network, the control of asynchronous motor is always an important problem.In the starting process of asynchronous motor, if directly started, it will cause a large current, will affect the stability and safety of the power grid;The starting torque and operating efficiency are also low.In order to improve the above problems, the use of soft starter to start the asynchronous motor can realize the non-pole adjustment of starting voltage, thus limiting the starting current, which can improve the motor performance to a certain extent.In this paper, the current closed-loop is adopted as the control mode, and MATLAB is used to build the model and simulate the soft starting system of asynchronous motor, and then the advantages of soft starting are illustrated.)
