Design of train lateral semi-active suspension control system based on minimum variance control

In order to improve the stability of train at high speed running state and enhance the ride comfort, this paper carried out the simulation and analysis of the semi-active suspension control system by using the minimum variance control algorithm, and presents the design scheme of the semi-active suspension control system of high-speed trains based on the minimum variance control. The simulation platform was built by Matlab-Simulink. The simulation results show a considerable improvement of lateral vibration, as compared with the traditional passive suspension mode.
