摘要：
The high-speed EMU (electric multiple units) is a complex system composed of multi-section vehicles and hooking devices. This paper compares the hooking device into a spring-damper system, and analyzes the dynamic mechanism and mode of the action of coupler and buffer device on adjacent vehicles during the operation of high-speed EMU, and then, establishes the strong coupling model of high-speed EMU. According to the decentralized characteristics of the input of train model power or braking force, a distributed neural network sliding mode control strategy is designed to track the speed of high-speed EMU. In order to reduce the influence of unknown factors on the control accuracy of high-speed EMU during speed tracking, using the historical train operating data, the historical operating data center is used to compensate the current control law to improve control accuracy and practical stability. The simulation results of the high-speed EMU Operation Simulation Platform show that the modeling method can better reflect the operation characteristics of the high-speed EMU than the previous multi-point model, and the control strategy with compensation rules is better than the traditional control effect.
