Distributed Cruise Control of High-speed Train System under Constrained Conditions

This paper studies the distributed cruise control of the high-speed train systems with velocity and control input constraints and considers the function of couplers between neighboring carriages. A distributed cooperative law is introduced to realize safe and stable operation of the single high-speed train with multiple carriages and multiple high-speed trains with multiple carriages. Based on the method of model transformation, matrix analysis and convex analysis, it is shown that all carriages of high-speed train systems can reach the desired speed. Finally, two digital simulation examples are given to state the theoretical results.
