A Hybrid Position Feedback Controlled Bistable Metamaterial Concept

Résumé

The hybrid position feedback controller, proposed previously by the authors, is a control technique for bistable systems and it is based on the well-known positive-position-feedback controller. This controller is an unstable-then-stable position feedback controller, which is a second-order single-degree-of-freedom system in nature. The hybrid controller takes advantage of the resonant mode of a bistable system about one equilibrium position, destabilizes the system, and dynamically induces snap-through between the two equilibria. In this paper, a new multi degree of freedom metamaterial concept that utilizes the hybrid position feedback controller is introduced. An arbitrary number of bistable "segments" or "material elements" are attached to each other in a serial (or parallel) manner to generate a "distributed" bistable structurealso referred to as a metamaterial. Due to the simplicity of the hybrid controller, the physical implementation of proposed approach can be realized using simple circuit elements distributed in the material domain. This new metamaterial inherits the multiple bistable positions that its building blocks have; hence, the metamaterial becomes multistable. It can hold multiple positions without consuming power and has the capability of achieving many shapes. The proposed metamaterial concept can be used in various applications: locomotion in bioinspired systems, undulatory motion, morphing aerodynamic surfaces, wave guiding, and vibration attenuation. The concept can also be used in energy harvesting to enable maximum power extraction for a given vibratory input.
