Discrete Fuzzy Model Optimal Identification Based Approach for High Speed Train Operation
This paper investigates the problem of high speed train operation with special attention to minimizing the discrete constraint conditions between on-board traction network and group signaling equipment. A new discrete fuzzy model for train operation is developed, and its novelty lies in the fact that it optimizes the discrete model using relative degree criterion, which contains two processes of model order identification and model parameters local optimization. Then, we utilize a fuzzy weighted least square method to solve the global optimization problem of model parameters. In the end, simulation experiments have been implemented on the CRH2C-type high speed train, which validates the correctness of the proposed model.
