This paper presents an “accelerated” adaptive control (AAC) for a class of nonlinear uncertain systems with guaranteed well-shaped transient response and controllable tracking process. By invoking an appropriate rate function from a function pool provided into the control law and the adaptive law, a control scheme with double adaptation units is developed, which not only ensures full state zero-error...
This paper studies the problem of high-speed train operation with special attention to minimizing the energy consumption. The performance characteristics of a high-speed train, including traction characteristic and regenerative braking, and the railway geographical conditions consisting of slope, curve, and tunnel parameters, are fully considered in the dynamic model in order to make it more effective...
Adhesion control is a key technology for preventing or reducing wheel slip/skid and improving reliability of traction/braking systems of railway vehicles. With the running speed and operation span of trains increasing, the issue of wheel-rail adhesion becomes rather complex, making traditional re-adhesion based adhesion control strategy inapplicable for HST. This work proposes a novel active adhesion...
