We apply recent results on robust global asymptotic stabilization of the attitude of a single rigid body to the problem of synchronizing the attitude of a network of rigid bodies using graph-local information. The proposed synchronization scheme relies on a hysteretic hybrid feedback based on the unit quaternion representation of rigid body attitude to achieve a global synchronization result that is robust to measurement noise. While the hysteretic feedback manages a trade-off between robustness to measurement noise and unwinding, the scheme necessitates the communication of a single binary logic variable between neighboring rigid bodies.
Although there has been a significant amount of work in the area of stochastic optimal control theory towards the development of new algorithms, the problem of how to control a stochastic nonlinear system remains an o...

This paper addresses the ℒ 2 -induced gain analysis for switched linear systems. We exploit non-conservative necessary and sufficient conditions for the induced gain to lie below a prescribed positive constant and discuss on the induced gains of switched systems obtained for different classes of switching signals, which distinct regularity assumptions are placed on. We particularly show that the induced gain that is obtained for the class of every piecewise constant switching signal can also be attained by the more restricted classes of switching signals.
We introduce periodic plasmonic waveguides which support a guided subwavelength slow-light mode over a very broad range of frequencies. The structure consists of a metaldielectric-metal waveguide side-coupled to a per...

This paper addresses the computation of the ℒ 2 -induced gain for switched linear systems. The main contribution of the paper is to completely characterize the induced gain of a switched system though a differential inequalities on a finitely parametrized common storage function, one equation for each system being switched. The motivation for computing the induced gain of a switched system is the application of robust stability tools to the analysis of hybrid systems.

We present an efficient adaptive method to compute the harmonic volumetric mapping, which establishes a smooth correspondence between two given solid objects of the same topology. We solve a sequence of charge systems based on the harmonic function theory and the method of fundamental solutions (MFS) for designing the map with boundary and feature constraints. Compared to the previous harmonic volumetric mapping computation using MFS, this new scheme is more efficient and accurate, and can support feature alignment and adaptive refinement. Our harmonic volumetric mapping paradigm is therefore more effective for practical shape modeling applications and can handle heterogeneous volumetric data. We demonstrate the efficacy of this new framework on handling volumetric data with heterogeneous structure and nontrivial topological types.
