Abstract
The optimal design of passive vibration control is a challenge for both application and research. These design methods are based on of structure optimization and models are typically solved in frequency domain. This work explores the benefits of introducing state-space methods on passive control. We propose an optimization approach based on the design of the limit cycles of mechanical systems under periodic forces. We exploit the analogy between damping optimization and energy harvesting to address simultaneously both technologies. An example of energy harvesting optimization is presented.
