泵站用交流电动机控制方法的改进

The Improvement of AC Motor's Control in Pumping Stations

泵站中所用的交流电动机,其带动的一般是较大的负载。如果交流电动机的起动和制动不平稳,就有可能对电机、泵和其它一些装置产生较大的冲击,这会对这些装置造成损害。由于传统的PID控制效果并不理想,作者提出了用模糊最近邻聚类学习算法设计最小方差控制器,并进行仿真实验,取得了不错的结果。

As the AC motors have a big load, in pumping stations,if the starting and braking of AC Motor is not stablest will cause big shock for pump and other facilities resulting in damage pump or other facilities. As the conventional PID control do not assure stable, the authors give a new method that use fuzzy nearest-neighbour clustering to design minimum variance self-tuning controller, and the simulation shows a good result.
