基于模糊PI控制的交流调速系统研究

传统PI控制器以固定不变的PI参数去处理变化多端的动态过程，很难满足各种工况下的性能指标。针对这一问题，本文将模糊控制理论引入到交流调速系统的PI控制器中，实现PI参数的实时调整，显著地改善调速系统的动态性能。仿真实验表明，在同等实验条件下，模糊PI控制的动态性能优于传统PI控制的性能。

Study on Fuzzy-PI Control Method in AC Speed Regulation System

Because of the fixed PI parameters, the traditional PI controller is really difficult to dispose the protean dynamic process and meet the performance index under the various kinds of working conditions. Aiming at this problem, in the paper, the fuzzy control theory is introduced into the PI controller of AC speed regulation system to achieve the real-time adjustment of PI parameters and remarkably improve the dynamic performance of the system. The simulation results show that the control effect of the fuzzy-PI controller is much better than the traditional one under the same experiment conditions.
