Linear Modeling of a Flexible Substructure Actuated through Piezoelectric Components for Use in Integrated Control/Structure Design
For engineers designing integrated control/structure systems, this provides a modeling approach that simplifies assembly of actuated flexible substructures, though it is an incremental extension of existing TITOP modeling.
This study develops a generic TITOP model for substructures with embedded piezoelectric actuators, enabling easy assembly in flexible multi-body systems. The model is demonstrated on a flexible beam with bonded piezoelectric strips and vibration attenuation in a chain of beams.
This study presents a generic TITOP (Two-Input Two-Output Port) model of a substructure actuated with embedded piezoelectric materials as actuators (PEAs), previously modeled with the FE technique. This allows intuitive assembly of actuated flexible substructures in large flexible multi-body systems. The modeling technique is applied to an illustrative example of a flexible beam with bonded piezoelectric strip and vibration attenuation of a chain of flexible beams.
