Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：重载列车分布式异步协同制动控制技术
重载列车 分布式异步协同 制动控制技术
2023/4/19
ECP重载列车分散式制动控制主要研究具有电气制动系统（ECP）的长大货运列车在制动过程中如何减小纵向冲动的控制问题。由于重载列车车厢之间存在车钩力，整个列车动态模型存在耦合作用，导致分布式控制器设计难以实现。目前大多方法还集中在列车整体设计方案的研究中。而分布式异步制动设计是我们研究的动力和目标。分布式异步设计将会对列车制动控制带来巨大改变，优势极为明显，如：减少计算量和计算速度，降低信号带宽，可...
