THE CRUISE AND ACTIVE SUSPENSION CONTROL FOR HIGH SPEED TRAIN

摘要

This paper presents a complete analysis of the cruise control and the active suspension control for the high speed train (HST). For a train system, the system are designed to being safe and reliable with high efficiency and fault tolerance; however, users require faster, more stable and more comfort transportation. To make sure the safety at such high speed, automatic train control (ATC) is needed and used for the modern HST to guarantee the safety and monitor the cruise status. For HST, the conventional (passive) suspension techniques have reached the limit of its optimization and development; therefore, the active suspension system is necessary for HST to obtain better comfort. In this paper, the extended sliding mode control is studied and applied to the cruise and active suspension of the HST.
