Abstract
The study of slewing control of an active flexible structure has attracted the interest of researchers in the areas of engineering, aeronautics and aerospace. In this work was conducted mathematical modelling, numerical simulations and comparison between free dynamics, with linear control application and nonlinear control in the flexible structure system with active actuator. The linear control is designed using the control method of Linear Quadratic Regulator (LQR). The nonlinear control is designed using the control method of State Dependent Riccati Equations (SDRE). The control is proposed for two different applications; the first one is for the electric voltage of the motor and the second one is for vibration control and position of the structure (beam) applying an electric voltage in piezoelectric material. Numerical simulations demonstrated the effectiveness of the proposed control strategy, demonstrating that the linear and nonlinear controllers have the same effect on the active flexible structure system.
