Integrative design of communication mechanism and coordinated control law is an interesting and important problem for multi-agent networks. In this paper, we consider distributed coordination of discrete-time second-order multi-agent systems with partially measurable state and a limited communication data rate. A quantized-observer based encoding-decoding scheme is designed, which integrates the s... View full abstract»

Cited by:  Papers (66)
| | PDF (3218 KB) | HTML

In this paper, exponential stabilizability of continuous-time positive switched systems is investigated. For two-dimensional systems, exponential stabilizability by means of a switching control law can be achieved if and only if there exists a Hurwitz convex combination of the (Metzler) system matrices. In the higher dimensional case, it is shown by means of an example that the existence of a Hurw... View full abstract»

Given a family of real or complex monic polynomials of fixed degree with one affine constraint on their coefficients, consider the problem of minimizing the root radius (largest modulus of the roots) or root abscissa (largest real part of the roots). We give constructive methods for efficiently computing the globally optimal value as well as an optimal polynomial when the optimal value is attained... View full abstract»

Cited by:  Papers (67)
| | PDF (2752 KB) | HTML

In this paper, we analyze the diagnosability properties of labeled Petri nets. We consider the standard notion of diagnosability of languages, requiring that every occurrence of an unobservable fault event be eventually detected, as well as the stronger notion of diagnosability inKsteps, where the detection must occur within a fixed bound ofKevent occurrences after the fault. We give... View full abstract»

• ### A Simultaneous Balanced Truncation Approach to Model Reduction of Switched Linear Systems

Cited by:  Papers (18)
| | PDF (3213 KB) | HTML

This paper deals with model reduction by balanced truncation of switched linear systems (SLS). We consider switched linear systems whose dynamics, depending on the switching signal, switches between finitely many linear systems with a common state space. These linear systems are called the modes of the SLS. The idea is to seek for conditions under which there exists a single state space transforma... View full abstract»

• ### Optimal Approximation Schedules for a Class of Iterative Algorithms, With an Applicationto Multigrid Value Iteration

Publication Year: 2012, Page(s):3132 - 3146
Cited by:  Papers (10)
| | PDF (3787 KB) | HTML

Many iterative algorithms employ operators which are difficult to evaluate exactly, but for which a graduated range of approximations exist. In such cases, “coarse-to-fine” algorithms are often used, in which a crude initial operator approximation is gradually refined with new iterations. In such algorithms, because the computational complexity increases over iterations, the algorithm's convergenc... View full abstract»

The aim of this note is to investigate the agreement between state and parameter estimates for a class of infinite dimensional systems that utilize distributed adaptive filters. It is assumed that the unknown parameters take the form of a structured perturbation with an unknown constant parameter, and the nominal system satisfies an infinite dimensional analog of positive real lemma. The proposed ... View full abstract»

We study the stability of a class of networked control systems with hard bounds on the control authority. The plant dynamics are discrete-time, linear, and time-invariant, with stochastic process noise and measurement noise. The controller is designed as a norm-bounded causal history-dependent function of the past outputs perturbed by bounded noise. The resulting control signals are assumed to be ... View full abstract»

The problem of realizing arbitrary transfer functions as combinations of positive filters, or, more in general, of representing arbitrary systems by means of Internally Positive Representations (IPRs), has been widely investigated in the discrete-time framework. An IPR is a positive state-space representation, endowed with input, state and output transformations, that realizes arbitrary input-stat... View full abstract»

In this note, we study the consensus problem for multiagent systems with measurement noises. Different from the existing approach, the consensus problem is converted to a root finding problem for which the stochastic approximation theory can be applied. By choosing an appropriate regression function, we propose a consensus algorithm which is applicable to systems with more general measurement nois... View full abstract»

We present a distributed discontinuous control algorithm for a team of agents to track the average of multiple time-varying reference signals with bounded derivatives. We use tools from nonsmooth analysis to analyze the stability of the system. For time-invariant undirected connected network topologies, we prove that the states of all agents will converge to the average of the time-varying referen... View full abstract»

This note considers the output tracking problem for a nonminimum-phase underactuated surface ship, where the actuation is provided by a stern propeller and rudder. As tracking output, we choose the position of a point placed on the longitudinal symmetry axis, at a positive distance from the position of the ship's geometric center. We show that the exact tracking problem for a smooth reference traj... View full abstract»

This technical note studies the distributed averaging problem over general random networks, by means of augmenting state space. A general iterative scheme (with a certain structure) is proposed that is discrete-time, linear, and stochastic; its generality compared to the literature lies in that the weight matrices corresponding to the networks need not be column-stochastic, and the random process ...

In this note, we address the problem of global output feedback tracking for a class of low-triangular nonlinear systems. Instead of using backstepping approach, we propose a novel dynamic gain scaling technique to design the output feedback controller. With a change of coordinates, a linear-like controller is constructed, which avoids the repeated derivatives of the nonlinearities depending on the... View full abstract»
