The Thesis Of The Contrl System Of Active Control Pantograh

With great-leap-forward development of China's high-speed rail, high-speed trains has considerable development both in quantity and in speed. However, the power of high-speed trains comes from the system which is formed by the pantograph and the catenary.The pantograph and the catenary are in a Dynamic interaction which is a kind of vibration of a particular form. If The contact pressure between the pantograph and the catenary is too large, the wear between them will be serious.This will shorten the life of the pantograph and Increase the costs even cause accient. If the contact pressure between the pantograph and the catenary is too low, it will cause unstable contact which will cause current instability. Then the power of high-speed train is affected. So there must be a appropriate pressure and goog dynamic characteristics. Domestic and foreign research and practice have proved that active-control-pantograph is a good way to solve this problem.This article is focused on the control system of the active-control-pantograph. We developed a control system for the pantograph active control based on active control theory and C8051F060MCU.
