             abstract = "Control of flexible structures is an open problem. Such structures 
                         can be very different, for example, robot arm or satellite solar 
                         panel. The common point between these structures is their very 
                         light weight and large length. Light structure control requires 
                         less energy, smaller actuators but a much more complex control 
                         system to deal with vibrations. In this paper a flexible rotatory 
                         beam is modeled by Euler-Bernoulli hypothesis and its angular 
                         position is controlled. This kind of model is, most of the time, 
                         highly non-linear. As a result, controller designed by linear 
                         control technique can have its performance and robustness 
                         degraded. To deal with this problem, the State-Dependent Riccati 
                         Equation (SDRE) method is used to design and test a position 
                         control algorithm for the rigid-flexible non-linear model. The 
                         Matlab/Simulink simulation is based on the characteristics of real 
                         flexible link equipment driven by a DC servomotor. This work 
                         serves to show the relevance this non-linear controller showing 
                         advantages it has over a more classic LQR controller. In future 
                         work, this controller will be tested with the real rotatory beam 
                         to validate the model and the SDRE control efficiency.",
