Abstract :
In this paper, we propose to explore some recent results on the control of systems with saturations on control input. The purpose is to carry out the active vibration control in a classical smart flexible structure. The practical problem considered here is that of a flexible beam with one edge embedded into a movable support and the other free. This beam is equipped with two piezoelectric patches: one of them is used as an actuator and the other is used as a sensor. For reasons of experimental implementation, the control input is constrained by a symmetric and bipolar saturation at a given level. The main goal of this work is to design an anti-windup augmented controller in order to recover some linear closed-loop performances in the presence of this non-linearity.
