Abstract : "This paper deals with the control of nonlinear systems using multimodel approach. The main idea of
this work consists on the association of the gap metric and the stability margin tools to reduce the number of
models constituting the multimodel bank. In fact, the self-organisation map (SOM) algorithm is used, firstly, to
develop a preliminary multimodel bank. Then, the gap metric and the stability margin are computed to determine
the redundancy of the initial multimodel bank. So, the multimodel controller is elaborated based on the reduced
model bank. Simulations confirm the method for selecting the appropriate number of local models which should be
used in the controller design."
