Abstract :
In this paper, a robust loop shaping controller is designed to suppress the first two vibrating modes of a piezo actuated structure. The vibrating modes are measured by two homogeneous piezoelectric sensors. The states estimated using information filter are fused, and applied as control input. The performance of the controller is evaluated through simulation and it is found that the closed loop performance with data fusion gives improved results.
