Overviews of controlling technology in high-speed rail transportation

With the development of control technique in high-speed rail´s safety and convenience aspects, the technology of high-speed rail is developed rapidly and the operating speed is improved constantly. This paper researches the progress and application of high-speed rail transportation, including the development and research achievement of pantograph active control and the development trend of single motor control and coordination control in the traction drive. Also, some current control methods are summarized and several kinds of train operation control systems are compared. Finally, this paper prospects the development trend of high-speed rail controlling technology.
