Gyroscopic Stabilization of Unstable Vehicles: Configurations, Dynamics, and Control
We consider active gyroscopic stabilization of unstable bodies such as two-wheeled monorails, twowheeled cars, or unmanned bicycles. It has been speculated that gyroscopically stabilized monorail cars would have economic advantages with respect to birail cars, enabling the cars to take sharper curves and traverse steeper terrain, with lower installation and maintenance costs. A two-wheeled, gyr...

متن کاملStrongly stable gyroscopic systems
Here, gyroscopic systems are time-invariant systems for which motions can be characterized by properties of a matrix pencil L(λ) = λ2I + λG − C, where GT = −G and C > 0. A strong stability condition is known which depends only on |G| (= (GT G)1/2 ≥ 0) and C. If a system with coefficients G0 and C satisfies this condition then all systems with the same C and with a G satisfying |G| ≥ |G0| are al...
متن کاملTopological mechanics of gyroscopic metamaterials.
Topological mechanical metamaterials are artificial structures whose unusual properties are protected very much like their electronic and optical counterparts. Here, we present an experimental and theoretical study of an active metamaterial--composed of coupled gyroscopes on a lattice--that breaks time-reversal symmetry. The vibrational spectrum displays a sonic gap populated by topologically p...
