多变量模糊控制在城市轨道列车牵引中的应用

The Appliation of Multi-variability Fuzzy Policy in Train Haulage

介绍了城市轨道列车自动变速控制的一种方法———多变量模糊控制。在基本速度模糊控制器的基础上 ,加入位移模糊控制和加速度模糊控制 ,构成多变量模糊控制器。经仿真试验验证 ,该控制方法控制精度高、速度跟踪性能好、运行安全性高 。

The multi-variability fuzzy policy is used in the automatic speed change of city railway train. On the basis of velocity fuzzy controller, it adds the distance control and acceleration control, and composes the multi-variability fuzzy controller. The author argues that the new controller, after the test of emulation, can achieve higher level control precision, better speed tracking performance and higher running safety, therefore, the multi-variability fuzzy policy is one of the best control tactics.
