基于Simulink的滑模软起动器仿真研究

Simulation of Sliding Mode Soft Starter Based Simulink

提出了一种滑模软起动装置,构建了斜坡起动、限流起动、转矩控制起动和分级变频起动四种软起动模型。通过滑模控制,使软起动装置能够满足在不同工作场合下电动机的起动要求,进而扩大软起动装置的使用范围。在Matlab/Simulink环境下对该软起动控制装置进行建模仿真。

A sliding mode soft starter is proposed,and four soft starting models,i.e.slope starting,current limiting starting,torque control starting,discrete frequency starting,are built up.Through sliding mode control the soft starter can meet the start-up requirements in different working occasions,and so that expanding the application range of the soft starter.The modeling and simulation of the soft starter are carried out under the environment of Matlab/Simulink.
