Embodiment Construction

[0074] The implementation of the present invention selects a CRH-type EMU on the Beijing-Shanghai high-speed railway line as the experimental verification object, collects 2000 sets of speed and control force data of the changed train set in a certain line section, and uses 1200 sets of data as modeling data samples, and the remaining 800 group data as test data.

[0075] First, according to the collected 1200 sets of modeling sample data, the optimal rule number of the model can be determined to be 6 by using subtractive clustering. Based on this, the antecedent and posterior parameters of the model are obtained by using the gradient descent algorithm and the least square method, and the input and The membership functions of Figure 4 and Figure 5 As shown, the fuzzy model rules are shown in Table 1, and the antecedent parameters of the fuzzy rules and As in Table 2. In order to verify the effectiveness of the model, the remaining 800 sets of operating data ...

Abstract

The invention provides a generalized predicative control method of a high-speed train based on an adaptive network-based fuzzy inference system (ANFIS) model. The method utilizes a data-driven modeling method to build the ANFIS model in a running process of the high-speed train according to acquired high-speed train running data; adopts subtractive clustering to determine rule number and initial parameters of a fuzzy model, and adopts a back-propagation algorithm and a least square method to optimize parameters of the fuzzy model. The predictive tracking control method of electric multiple unit running speed on the basis of the ANFIS model obtains accurate controlled quantity through multistep predication and circular rolling so as to change blindness of adjustment by experience, enables the high-speed train running speed to track a target curve accurately, solves the problem of large lag, achieves on-schedule, safe and effective running of the train, and guarantees safety of passengers. The method is simple, practical, capable of achieving automatic drive control of the high-speed train and suitable for on-line monitoring and automatic control of a running process of the high-speed train.
