Abstract: In order to improve the robustness of the Discrete Sliding Mode Control, essentially in the reaching phase, we propose in this paper a new version based on the multimodel and multicontrol approaches. A real time application of the Multimodel Discrete Sliding Mode Control (MM-DSMC) and of the Classical Discrete Sliding Mode Control (C-DSMC) is realised. The obtained results in the case of the real non-stationary system show good performances in terms of robustness and insensibility in the reaching phase. A comparative study of the classical and multimodel version of the control is given in this paper.

Keywords: multimodelling; multicontrol; sliding mode control; real time; non-stationary systems; discrete control.
