Stabilization of linear systems with limited information
By relaxing the definition of quadratic stability, it is shown how to construct logarithmic quantizers with only finite number of quantization levels and still achieve practical stability of the closed-loop system.
Control under communication constraints
This paper forms a control problem with a communication channel connecting the sensor to the controller, and provides upper and lower bounds on the channel rate required to achieve different control objectives.
Probabilistic Solution of Ill-Posed Problems in Computational Vision
This work derives efficient algorithms and describes parallel implementations on digital parallel SIMD architectures, as well as a new class of parallel hybrid computers that mix digital with analog components.

A unified framework for hybrid control: model and optimal control theory
This work introduces a mathematical model of hybrid systems as interacting collections of dynamical systems, evolving on continuous-variable state spaces and subject to continuous controls and discrete transitions, and develops a theory for synthesizing hybrid controllers for hybrid plants in all optimal control framework.

It is shown that optimal quadratic cost decomposes into two terms: A full knowledge cost and a sequential rate distortion cost.

There is disclosed a charged particle beam apparatus capable of adjusting the convergence angle of the charged particle probe independent of the current in the probe. The apparatus comprises a…
The Necessity and Sufficiency of Anytime Capacity for Stabilization of a Linear System Over a Noisy Communication Link—Part I: Scalar Systems
In cases of sufficiently rich information patterns between the encoder and decoder, adequate anytime capacity is shown to be sufficient for there to exist a stabilizing controller and this result is generalized to cases with noisy observations, delayed control actions, and without any explicit feedback between the observer and the controller.
Control over noisy channels
This work presents a general necessary condition for observability and stabilizability for a large class of communication channels, and studies sufficiency conditions for Internet-like channels that suffer erasures.
Volatility of Power Grids Under Real-Time Pricing
The paper proposes a framework for modeling and analysis of the dynamics of supply, demand, and clearing prices in power systems with real-time retail pricing and information asymmetry and highlights the need for assessing architecture systematically and in advance to optimally strike the trade-offs between volatility/robustness and performance metrics such as economic efficiency and environmental efficiency.
