A novel frequency-domain technique, having its roots in Quantitative Feedback Theory (QFT), has been developed to design controllers for active vibration control (AVC). The advantages are a plant-based design according to performance specifications, and the ability to include structured uncertainties in the critical plant parameters like passive bearing stiffness or damping. In this paper, we describe the background theory of single-input, single-output (SISO) and multi-input, multi-output (MIMO) QFT design, followed by development of the theory adapted for AVC. Application examples are considered next, outlining the design method for both cases. Simulation results for the systems studied are presented showing the effectiveness of the technique in attenuating vibration.

Active Vibration

This article describes a design method to size smart structures with piezoelectric ceramics. The method makes it possible to determine the amplitudes of vibrations that may be generated by piezoelectric ceramics bonded on a metallic or composite structure. One of the possible applications of the method is the preliminary design of smart structures for active vibration control. This case is particularly treated in this article. The method is based on a reduced model that can be established using a multiphysics FEM software. This model can also be used to compute the control law for vibrations attenuation.
