Abstract: An approach to internal model controller synthesis for non-linear systems is proposed in this paper. This approach is based on the multimodel modelling of non-linear systems and the realisation of a specific inverse of each model. The inversion of each model is necessary in the internal model controller design. A comparative study is presented between two structures of internal multimodel controller for non-linear control system based on two different fusion methods. The first one is based on the switching methods and the second one is based on the residues techniques. The case of a non-linear system is presented to show the effectiveness of these control structures and to compare these structures of internal multimodel control of this non-linear system.

Keywords: internal model control; inverse model; multimodel control; nonlinear systems; residues techniques; modelling; controller design.
