This paper deals with the coordinated control of the multiple high-speed train system taking into account the sampled characteristic of the communication information. Considering the inertial lag of the servo motor/braking unit in practical scenarios, a third-order nonlinear model is adopted to capture the dynamics of a train, based on which the coordinated control problem is formulated. By virtue of the back-stepping linearization technique, the sampled-data communication based train coordination is transformed to the stabilization of a linear multiple-input system subject to periodic time-varying input delay. An event-triggering communication framework is constructed to lower the dependence on the communication resource. Furthermore, distributed low-gain feedback control protocols are established that, besides achieving coordination of the train operation, ensure the trains track the predefined train speed profile while avoiding unnecessary information transmission. Numerical experiments are carried out to verify the theoretical results.

基于事件触发通信的多列高速列车分布式协调控制


本文研究了考虑通信信息采样特性的多路高速列车系统的协调控制。考虑到实际场景中伺服电机/制动单元的惯性滞后，采用三阶非线性模型来捕获列车的动力学，并在此基础上制定协调控制问题。借助反步线性化技术，将基于采样数据通信的列车协调转化为受周期性时变输入延迟影响的线性多输入系统的稳定性。构建事件触发通信框架，降低对通信资源的依赖。此外，建立了分布式低增益反馈控制协议，除了实现列车运行的协调外，还确保列车跟踪预定的列车速度曲线，同时避免不必要的信息传输。进行了数值实验来验证理论结果。
