摘要
针对铁路机车受电弓系统存在的振动问题 ,提出了一种基于模糊技术的旨在抑制振动的主动控制方案。在对接触网 -受电弓系统特征进行分析的基础上 ,设计开发了以 P 30 0工控机为主控器件的受电弓主动模糊控制系统 ,并以 SS7型机车受电弓为对象进行了试验。试验结果表明 :采用主动控制技术以后 ,受电弓弓头接触压力波动值大大降低 。
An active vibration control method is put forward to restrain the vibration of the pantograph catenary system of rail locomotive . According to the characteristic analysis of the pantograph catenary system , a fuzzy controller is designed to undertake real time fuzzy inference and operation . The test for SS7 locomotive pantograph is carried out with the fuzzy controller in laboratory . The results show that the vibration amplitude of the pressure between the pantograph and catenary is greatly reduced, and the dynamical performance of the pantograph catenary system is considerably improved by using the active vibration control method developed in this paper.
