A Multi-Input FFFB Control Algorithm for Railway Rapid Transit Vehicle Speed Regulation

Abstract:

The purpose of this research is to develop a multi-input control algorithm for the speed regulation of railway transit vehicle. The Taipei railway transit vehicle is chosen as the simulation object in this research. This transit vehicle has three carts and is push-pull type; only the first and the last carts are empowered. The control algorithm is to calculate the appropriate driving forces for the power units such that vehicle can follow a specified speed pattern. A feed-forward and feed-back control algorithm is designed to achieve this purpose. In the system, a dynamics variable observer is also developed to reduce required sensors for the controller. The results show that the developed controller is suitable for this purpose and the observer achieves acceptable observation quality for the controller application.
