Sliding Mode Control of High Speed Train with Additional Resistance

The additional resistance force of high-speed train (HST) operation process affects driving safety to study its disturbance degree of speed and displacement, high-speed train is firstly regarded as a single mass point model. Afterward, the needed goal speed and goal displacement are designed according to Lan-Xin Line train operation real measurement data. Finally, the sliding mode controller is proposed based on Lyapunov stability theory to reduce the influence of additional resistance force in speed and displacement tracking. The simulation result shows that the proposed method can effectively overcome disturbance signal, and guarantee high-speed train safe operation, meanwhile, the goal speed and displacement of high-speed train are accurately tracked.
