The scope of this paper is to present a fuzzy logic control of a class of multi-input multi out put (MIMO) nonlinear systems\ncalled ââ?¬Å?system of ball on a sphere,ââ?¬Â such an inherently nonlinear, unstable, and under actuated system, considered truly to be two\nindependent ball and wheel systems around its equilibrium point. In this work, Sugeno method is investigated as a fuzzy controller\nmethod, so it works in a good state with optimization and adaptive techniques, which makes it very attractive in control problems,\nparticularly for such nonlinear dynamic systems.The systemââ?¬â?¢s dynamic is described and the equations are illustrated.The outputs are\nshown in different figures so as to be compared. Finally, these simulation results show the exactness of the controllerââ?¬â?¢s performance.
