Abstract
The ship propulsion system is a nonlinear and uncertain system. To overcome these constraints, in order to synthesize a powerful command, the multimodel control is promising. This paper deals with the modeling and multimodel control of complex uncertain systems. The approach is based on the principle of generating model bases, which can be local or generic, determined according to procedures using Kharitonov’s algebraic approach. The evaluation of the relevance of the models is ensured by means of validations calculated on line by referring to the responses of the process. Such validities are used to generate the multimodel control according to a strategy by fusion. Two fusion methods are then proposed: A merge at the level of the elementary commands and another at the level of the control parameters. This work deals with the development of a model base, as well as the synthesis of a multimodel control law. In this sense it is proposed to study the electric propulsion of ships as well as its composition. Next, we propose a technique for modeling the electric propulsion system of a ship and synthesized a multimodel control law. Finally, we will model the propulsion system based on a synchronous motor with permanent magnet and synthesize a law of control according to the multimodel approach.
