This paper deals with the problem of switched linear system identification. This is one of the most difficult problems since it involves both the estimation of the linear sub-models and the switching instants. In fact, we propose an identification approach based on self-adaptation multi-kernel clustering algorithm to estimate simultaneously the linear sub-models and the switching signal. The estimation of the sub-models consists of decomposing the regression vector into several blocks and assigning a kernel function to each block. However, the estimation of the switching signal is provided by an unsupervised classification algorithm with self-adaptive capacities. Simulation results are presented to illustrate the effectiveness of the proposed approach.
