| 摘 要： | 本文针对三相异步电动机起动电流较大的问题,设计了一种软起动模糊自适应控制器。软起动可以控制电动机的起动电流,减少起动过程中电流过大对电网和设备的损坏,保证电动机平稳运行。据其起动特性,将电流误差和误差的变化率作为输入量,晶闸管的控制角作为输出量,设计出一种自调整比例因子的模糊自适应控制算法。随后在Matlab环境下仿真其控制性能,并且与常规的PID控制方法和常规模糊控制方法进行比较,验证了模糊自适应控制算法的优越性。

| Abstract: | Considering the large startup current of induction motors, this paper presents a fuzzy Adaptive control soft starting system. It can control startup current and avoid the inrush of the current for smooth running. According to the characteristic of induction motor, taking current error and error change rate as input and the angle of thyristor as output,the fuzzy Adaptive control model for the soft startup of induction motor is established by using fuzzy logical toolbox in Matlab software.
