Feedforward and feedback active control of metro pantographs under abnormal excitations due to track conditions

机车电传动
Metros are predominantly equipped with low-elasticity overhead rigid catenaries, which can easily lead to poor pantograph-catenary relationship. In recent years, abnormal wear has occurred frequently between the pantographs and catenaries in metro ...

Study on Model Reference Adaptive Control for Subway Pantographs

Kongzhi Yu Xinxi Jishu
The coupling performance of subway pantographs with catenaries affects the quality of current collection and the safety of trains. The rigidity of these catenaries exhibits periodicity and fluctuations due to factors such as geographical locations ...
