| 英文摘要 |
| Antiskid control of high-speed trains (HST) guarantees the safe operation by the slip ratio adjustment. The
available antiskid control of trains applies on-board sensors to collect train state information such as vehicle speed and
wheel speed. Limited by the capability of train communication networks, there is input delay caused by the mismatches
between the real-time operating data and the collected data. Namely, the input delay affects the performance of antiskid
controllers, and even leads to the failure of antiskid control. To deal with the above problem, a train adhesion dynamics
model with input delay is established to analyze the adhesion features of the train in different operation conditions and
to design the antiskid scheme of HST with input delay in the whole operation. Firstly, the aforementioned system is
approached by the linearization, and the upper bound of the input delay and the corresponding controller parameters of
the above model are obtained; then, based on the upper bound of input delay, a predictor with time delay compensation
is designed to guarantee the effectiveness of train antiskid control. Due to the simulations, the available antiskid control
without considering input delay cannot work out the negative impact of input delay, the proposed antiskid control scheme
not only handles the negative impact of input delay effectively, but also is robust. |
