Research of Soft-staring for Asynchronous Motor with Torque Self-adaptive Fuzzy Control

Considering the existing problems as asynchronous motor start up directly,this paper studys a torque slope start-up mode for asynchronous motor based on self-adaptive fuzzy control.Through analysis of mechanical characteris-tics of asynchronous motor with constant torque,the paper establishes mathematic model of torque slope start-up mode for asynchronous motor based on self-adaptive fuzzy control.With the use of the power system blackest and the fuzzy logic toolbox in Matlab,the simulation model is built and simulink.The simulation results show that the soft-staring mode is correct and effective,reduces the shock to the electrical network and the adverse effects on the drag system and make asynchronous motor start up very smoothly.The oscilloscope test proved the conclusions correct.
