Abstract: Advancement of piezoelectric transducer technology enables distributed actuation and sensing along flexible structures for vibration suppression. This study addresses the controller design under the paradigm of cooperative control and optimisation. A finite element model of a cantilever beam, coupled with piezoelectric actuators and accelerometers is constructed and then validated with a physical setup. Based on the finite element model, distributed controllers are designed. Considering the existence of feed-through terms in the system, each controller applies its control action based not only on its local measurement and state estimations from a few neighboring agents, but also on the exact control actions of all the other controllers as well, to realize global vibration suppression. The control design problem is reformulated as optimising a scalar subject to a set of linear matrix inequalities (LMIs). The vibration suppression performance of the cooperative control scheme is examined in both time domain and frequency domain via simulations.
