On delayed observers for linear systems with unknown inputs
(2005)
We present a method for constructing reduced-order state observers for linear systems with unknown inputs. Our design provides a characterization of observers with delay, which eases the established necessary conditions ...
The wireless control network: Monitoring for malicious behavior
(2010)
We consider the problem of stabilizing a plant with a network of resource constrained wireless nodes. In a companion paper, we developed a protocol where each node repeatedly transmits an appropriate (stabilizing) linear ...
Nonconcurrent error correction in the presence of roundoff noise
(2006)
This paper analyzes the effects of roundoff noise on our ability to nonconcurrently detect and identify transient faults that corrupt state variables during the operation of a fault-tolerant discrete-time (DT) linear ...
Time-varying power-limited preprocessing for perfect reconstruction of binary signals
(2006)
In this paper we consider a deterministic worst-case framework for perfect reconstruction of discrete data transmission through a dispersive communication channel. More specifically, we extend our previous work to capture ...
A novel 3-d model for node and system trust
(2011)
Nowadays, there is an increasing demand for wireless and mobile networks that guarantee secure and reliable data communication among users. To enable data exchanges, authentication mechanisms need to be in place to dynamically ...
Robust Linear Quadratic Regulator for uncertain systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
This paper develops a Linear Quadratic Regulator (LQR), which is robust to disturbance variability, by using the total variation distance as a metric. The robust LQR problem is formulated as a minimax optimization problem, ...
Non-concurrent error detection and correction in discrete-time LTI dynamic systems
(2001)
In this paper we develop fault-tolerant constructions for discrete-time (DT) linear time-invariant (LTI) dynamic systems that are build out of appropriately interconnected delay, adder and gain elements. More specifically, ...
Non-concurrent fault identification in discrete event systems using encoded Petri net states
(2002)
In this paper we extend a previously developed coding-based methodology for monitoring faults in discrete event systems that are described by Petri nets. We present a systematic design that enables us to non-concurrently ...
Marginal analysis on binary pairwise Gibbs random fields
(2011)
In this paper, we study marginal problems for a class of binary pairwise Gibbs random fields (BPW-GRFs). Given a BPW-GRF associated with a family of binary positive pairwise potentials, finding the exact marginal for each ...
