研究了异步电机交流调压软起动电路恒流起动的控制算法,提出了以电流截止角为内环和以电流为外环的双环控制结构,设计了一种三维模糊PID电流控制器,仿真实验结果表明该控制方法能保证电机具有很好的起动特性,优于传统的PID单环控制.

In this paper, AC motor voltage-regulatin constant current soft starting controlling circuit system is studied. The two closed--loops control structure including current cut-off angle inner control loop and current external control loop is presented. Three dimensions Fuzzy-PID controller is designed to obtain excellent start-up performances. Simulations confirm t...
