Abstract EN
Train operation is a complex nonlinear process; it is difficult to establish accurate mathematical model.
In this paper, we design ATO speed controller based on the input and output data of the train operation.
The method combines multimodeling with predictive functional control according to complicated nonlinear characteristics of the train operation.
Firstly, we cluster the data sample by using fuzzy-c means algorithm.
Secondly, we identify parameter of cluster model by using recursive least square algorithm with forgetting factor and then establish the local set of models of the process of train operation.
Then at each sample time, we can obtain the global predictive model about the system based on the weighted indicators by designing a kind of weighting algorithm with error compensation.
Thus, the predictive functional controller is designed to control the speed of the train.
Finally, the simulation results demonstrate the effectiveness of the proposed algorithm.
