| | PDF (847 KB) | HTML

The subject of this paper is the synthesis of natural projections that serve as nonblocking and maximally permissive abstractions for the hierarchical and decentralized control of large-scale discrete event systems. To this end, existing concepts for nonblocking abstractions such as natural observers and marked string accepting (msa)-observers are extended by local control consistency (LCC) as a n...

• ### Delay-Integral-Quadratic Constraints and Stability Multipliers for Systems With MIMO Nonlinearities

Publication Year: 2011, Page(s):738 - 747
Cited by:  Papers (14)
| | PDF (305 KB) | HTML

The formula for stability multipliers for systems with MIMO nonlinearities is derived using the method of delay-integral-quadratic constraints. The results, applicable to both time-invariant and time-periodic systems, are then used to derive a solution for a special case of a nonlinear regulation problem and a criterion for stability of forced oscillations. A linear time-periodic system is conside... View full abstract»

• ### Retroactivity Attenuation in Bio-Molecular Systems Based on Timescale Separation

Publication Year: 2011, Page(s):748 - 761

| | PDF (701 KB) | HTML

As with several engineering systems, bio-molecular systems display impedance-like effects at interconnections, called retroactivity. In this paper, we propose a mechanism that exploits the natural timescale separation present in bio-molecular systems to attenuate retroactivity. Retroactivity enters the dynamics of a bio-molecular system as a state dependent disturbance multiplied by gains that can... View full abstract»

• ### Worst-Case Identification of Errors-in-Variables Models in Closed Loop

Publication Year: 2011, Page(s):762 - 771
Cited by:  Papers (9)
| | PDF (599 KB) | HTML

A worst-case identification method in frequency domain is proposed to cope with the identification of errors-in-variables models (EIVMs) in closed loop. With a priori bound for the disturbing noises of an EIVM in closed loop, a frequency-domain normalized coprime factor model (NCFM) with perturbation is derived and thus the identification of the EIVM becomes that of the NCFM. By employing the v-ga... View full abstract»

This paper investigates the minimum data rate for mean square stabilizability of linear systems over a lossy digital channel. The packet dropout process of the channel is modeled as a time-homogeneous Markov process. To overcome the difficulties induced by the temporal correlations of the packet dropout process and stochastically time-varying data rate due to packet dropouts, a randomly sampled sy...

A robust, stabilizing output feedback controller for systems in the normal form, which could potentially include unstable zero dynamics, is presented. The control scheme adopted herein incorporates continuously-implemented sliding mode control-chosen for its robustness properties as well as its ability to prescribe or constrain the motion of trajectories in the sliding phase-and an extended high g...

• ### Characterizing and Computing the ${cal H}_{2}$ Norm of Time-Delay Systems by Solving the Delay Lyapunov Equation

Publication Year: 2011, Page(s):814 - 825
Cited by:  Papers (19)
| | PDF (541 KB) | HTML

It is widely known that the solutions of Lyapunov equations can be used to compute the H2 norm of linear time-invariant (LTI) dynamical systems. In this paper, we show how this theory extends to dynamical systems with delays. The first result is that the H2 norm can be computed from the solution of a generalization of the Lyapunov equation, which is known as the... View full abstract»

| | PDF (944 KB) | HTML

In this paper, we investigate control across stochastic dropout channels. In particular, we consider the Mean Square Stability of a SISO plant in the case there is only one channel in the feedback loop and the case where both actuator and sensor channels are present. We seek optimal networked control schemes that are memoryless functions of channel state information and for each channel state are ... View full abstract»

In this paper, we consider the problem of reducing network delay in stochastic network utility optimization problems. We start by studying the recently proposed quadratic Lyapunov function based algorithms (QLA, also known as the MaxWeight algorithm). We show that for every stochastic problem, there is a corresponding deterministic problem, whose dual optimal solution “exponentially attract... View full abstract»

This technical note is concerned with the problem of robust stability of singularly perturbed descriptor systems with nonlinear perturbation. We first use the fixed-point principle to investigate the existence of the solution for the given singularly perturbed system, a linear matrix inequality condition is obtained for the existence and uniqueness of the solution. In addition, a sufficient condit... View full abstract»

This article considers an improvement in dead zone modification scheme for robust model-reference adaptive control of SISO and TITO systems, described by input-output uncertain linear models with actuator faults. In the conventional approach, adaptation of the controller parameters is ceased in the dead zone, which leads to steady state tracking error. This problem is resolved by tuning specific c...

This technical note investigates the problem of checking robust D-stability of a polytope of polynomial matrices. Finsler's projection lemma is taken to derive a new sufficient condition in terms of a linear matrix inequality (LMI) feasibility problem. The basic idea behind this condition is to lift the existing stability condition into the one of larger space by means of Finsler's lemma an... View full abstract»

The problem of jointly synthesizing a supervisor, a measurement scheduler, and a feedback controller for discrete-time linear systems is considered. It is shown that open-loop supervisory and scheduling laws are nonconservative for robust exponential stability and H2 and H∞ type performance requirements, and that they can be obtained separately from the f...

We consider a path-following problem in which the goal is to ensure that the error between the system output and the geometric path is asymptotically less than a prespecified constant, while guaranteeing a forward motion along the path and boundedness of all states. Comparing with the results on this problem, we exploit averaging techniques to develop an alternative simpler solution for a class of... View full abstract»

This technical note considers the delay margin problem for discrete-time finite dimensional linear time-invariant (FDLTI) single-input single-output (SISO) systems. This problem has been studied extensively in continuous time - it is well-known that, given a FDLTI plant and controller forming a strictly proper stable feedback connection, closed loop stability will be maintained for small delays; h...

Stability domain characterization in coefficients space of polynomials is considered. The proposed method generalizes some recent results on convex approximation of stability domain in coefficients space. The method provides a new LMI formulation of stability constraints for a very general stability region including disjoint regions. Numerical examples are provided, demonstrating the power of the ...

This technical note investigates how to produce control programs for complex systems in a systematic manner. In particular, we present an abstraction-based approach to the specification and optimization of motion programs for controlling robot marionettes.

Two sampled-data design procedures ensuring stabilization of passive systems are described in the general framework of passivity-based control (PBC) strategies. The first one makes reference to some modified output with respect to which passivity under sampling can be preserved. The second one can be interpreted as the sampled-data equivalent to the celebrated continuous-time stabilizing and dampi... View full abstract»

Cited by:  Papers (110)
| | PDF (184 KB) | HTML

Boolean networks have recently been attracting considerable interest as computational models for genetic and cellular networks. We consider a Mayer-type optimal control problem for a single-input Boolean network, and derive a necessary condition for a control to be optimal. This provides an analog of Pontryagin's maximum principle for single-input Boolean networks. View full abstract»

• ### On the Covariance Completion Problem Under a Circulant Structure

Cited by:  Papers (11)
| | PDF (293 KB) | HTML

Covariance matrices with a circulant structure arise in the context of discrete-time periodic processes and their significance stems also partly from the fact that they can be diagonalized via a Fourier transformation. This note deals with the problem of completion of partially specified circulant covariance matrices. The particular completion that has maximal determinant (i.e., the so-called maxi...
