This article describes the computationally efficient predictive control of an active structure with bonded piezoelectric transducers. A highly under-damped physical structure, such as a helicopter rotor blade is represented by a simplified laboratory model. After introducing the experimental hardware the identification procedure is described. Theory behind the Newton - Raphson MPC algorithm is summed up, and its laboratory implementation and experimental verification illustrated. Results of the experiments show, that the proposed predictive control approach is capable of achieving high sampling rates in practical use while still respecting process constraints and maintaining guaranteed stability.
