本文提出了一种基于模糊自整定的异步电机PI控制系统。该控制系统包含主模块和增益整定两部分模糊逻辑模块。主模糊逻辑部分作为速度控制器，同时，增益整定部分测量主模糊逻辑部分的输出。由于增益整定部分的作用，超调量和稳定时间等指标都得到一定的减小。控制效果更加稳定、超调量更小，从而应对参考输入的干扰和突变。与PI模糊控制对比，实验结果显示，本文中的控制系统效果更佳。

@@@@This paper presents simulation of a control er based on self-tuning PI-fuzzy for DC motor. The control er consists of two fuzzy logic blocks, main and gain tuning, respectively. The main fuzzy block acts as a speed control er, while the gain tuning block scales the output of main fuzzy. By introducing gain tuning, overshoot and settling time can be restrained. The objective of the control er is to provide stability, to reduce overshoot in response to disturbance and sudden change in reference. The performance is compared to PI-fuzzy control er. Results show improved performance.
