Embodiment Construction

[0067] The present invention is specifically implemented in the Jinan-Xuzhou East downlink section of the Beijing-Shanghai high-speed railway under the jurisdiction of a certain railway bureau, and the operating data is collected on-site on the EMU CRH380AL. It passes through Tai'an Station, Qufu East Station, Tengzhou East Station and Zaozhuang Station, but only stops at Tai'an Station for 2 minutes. The starting mileage is 393.74km, the mileage at Tai'an Station is 465.77km, and the final mileage is 693.74km. The operating conditions of high-speed EMUs are complex and subject to constraints such as line gradient (the maximum gradient has reached 20‰), operating time, and speed limit. There are 9 tunnels in the whole process, 11 electrical separation phase points, and 17 slope values ​​exceeding 12‰. Table 1 shows the running time and minutes of each station specified in the operation diagram, Figure 5 is the line speed limit map.

Abstract

The invention discloses a running process modeling and adaptive control method for a motor train unit. The running process modeling and adaptive control method comprises the following steps: according to characteristics that the running process of the motor train unit is complex, information is incomplete and nonlinearity is obvious, putting forward a T-S bilinear model identification method by a data-driven modeling method; according to constraints such as an actual running chart, a front route condition, a limited speed condition, and traction/ braking force saturation nonlinearity of the motor train unit, establishing a constraint model of the motor train unit; and according to the model design, studying a model prediction control algorithm immediately to improve performance indexes for multi-objective optimization control. By the running process modeling and adaptive control method, a set of reliable basis is provided for optimizing operation of trainmen of the motor train unit, ensuring safe and punctual running of the motor train unit, improving the running comfort and lowering energy consumption; and the running process modeling and adaptive control method is applicable to on-line identification and the multi-objective optimization control on the running state of the motor train unit.

Description

technical field [0001] The invention relates to a modeling and self-adaptive control method for the running process of a multiple train set, and belongs to the technical field of online identification and optimal manipulation of the running state of the multiple train set. Background technique [0002] China's new generation of high-speed trains can reach a speed of 350 kilometers per hour in continuous operation, and the test speed has exceeded 400 kilometers per hour. It is the EMU with the fastest commercial operation speed, the highest technological content, and the best system matching in the world. Compared with other modes of transportation (such as automobiles, airplanes, and medium- and low-speed passenger and freight trains), EMUs can meet transportation needs such as long distances, large volumes, high density, and short travel times. my country currently has the world's largest high-speed railway network with the highest operating speed. By 2020, 16,000 kilom...
