| Abstract: | The basic control principle of discrete variable frequency asynchronous motor soft-start is introduced In this paper.With the Matlab/Simulink simulation tool,a simulation model of this system is established.7,5,4,2 discrete variable frequencies are used in the soft-starter,and on the power frequency time,the simulation experiment of the asynchronous motor soft-starter based on single neuron PID is pelformed to limit the current.The simulation results show its control strategy validly reduces the starting current and realizes high starting torque.It has a good prospect to application of heavy loading asynchronous motor starting. |
