摘　　要：为提高半挂汽车列车主动安全性能,建立了一套半挂汽车列车主动气压制动控制系统。设计了一套能与半挂汽车列车传统气压制动系统兼容的主动气压制动执行机构,搭建了相应的硬件系统;建立了系统增、减压模型和电磁阀开关过程模型;利用实验数据,采用粒子群算法对模型参数进行了辨识;在此基础上,建立了基于模型的主动气压制动控制策略,并进行了测试验证。结果表明,提出的半挂汽车列车主动气压制动控制系统能实现精确的主动气压制动控制。In order to enhance the active safety of tractor-semitrailer combination,an active pneumatic brake control system is built in this paper.A set of active pneumatic brake actuators,compatible with traditional pneumatic braking system,are designed with corresponding hardware system constructed.The pressure boost and relief models of the system and the on-off process model for solenoid valve are set up,and the model parameters are identified with particle swarm algorithm based on experimental data.On this basis,a model-based active pneumatic brake control strategy is established and verified by tests.The results show that the active pneumatic brake control system proposed for tractor-semitrailer combination can achieve accurate control of active pneumatic brake.
