NP-completeness of sensor selection problems arising in partially observed discrete-event systems
IEEE Transactions on Automatic Control - Tập 47 Số 9 - Trang 1495-1499 - 2002
Tae-Sic Yoo, S. Lafortune
We consider the three properties of diagnosability, normality, and observability of discrete-event systems. In each case, we consider the problem of finding an observable event set with minimum cardinality such that the property under consideration holds. We prove that these search problems are computationally hard by showing that the corresponding decision problems are NP-complete.

Input-to-state dynamical stability and its Lyapunov function characterization
IEEE Transactions on Automatic Control - Tập 47 Số 9 - Trang 1499-1504 - 2002
L. Grune
We present a new variant of the input-to-state stability (ISS) property which is based on using a one-dimensional dynamical system for building the class /spl Kscr//spl Lscr/ function for the decay estimate and for describing the influence of the perturbation. We show the relation to the original ISS formulation and describe characterizations by means of suitable Lyapunov functions. As application...... hiện toàn bộ

Discontinuous feedback stabilization of minimum-phase semilinear infinite-dimensional systems with application to chemical tubular reactor
IEEE Transactions on Automatic Control - Tập 47 Số 8 - Trang 1293-1304 - 2002
Y. Orlov, D. Dochain
This paper develops discontinuous control methods for minimum-phase semilinear infinite-dimensional systems driven in a Hilbert space. The control algorithms presented ensure asymptotic stability, global or local accordingly, as state feedback or output feedback is available, as well as robustness of the closed-loop system against external disturbances with the a priori known norm bounds. The theo...... hiện toàn bộ

The polynomial approach to the LQ non-Gaussian regulator problem
IEEE Transactions on Automatic Control - Tập 47 Số 8 - Trang 1385-1391 - 2002
A. Germani, G. Mavelli
A new approach for the solution of the regulator problem for linear discrete-time dynamical systems with non-Gaussian disturbances is proposed. This approach generalizes a previous result concerning the definition of the quadratic optimal regulator. It consists of the definition of the polynomial optimal algorithm of an order /spl nu/ for the solution of the linear quadratic non-Gaussian stochasti...... hiện toàn bộ

A novel error observer-based adaptive output feedback approach for control of uncertain systems
IEEE Transactions on Automatic Control - Tập 47 Số 8 - Trang 1310-1314 - 2002
N. Hovakimyan, F. Nardi, A.J. Calise
We develop an adaptive output feedback control methodology for nonaffine in control of uncertain systems having full relative degree. Given a smooth reference trajectory, the objective is to design a controller that forces the system measurement to track it with bounded errors. A neural network with linear parameters is introduced as an adaptive signal. A simple linear observer is proposed to gene...... hiện toàn bộ

A new parameterization of stable polynomials
IEEE Transactions on Automatic Control - Tập 47 Số 9 - Trang 1546-1550 - 2002
T.E. Djaferis, D.L. Pepyne, D.M. Cushing
In this note, we develop a new characterization of stable polynomials. Specifically, given n positive, ordered numbers (frequencies), we develop a procedure for constructing a stable degree n monic polynomial with real coefficients. This construction can be viewed as a mapping from the space of n ordered frequencies to the space of stable degree n monic polynomials. The mapping is one-one and onto...... hiện toàn bộ

Tracking trajectories of feedforward systems
IEEE Transactions on Automatic Control - Tập 47 Số 8 - Trang 1338-1342 - 2002
F. Mazenc, S. Bowong
The objective of this paper is to solve the problem of tracking trajectories of feedforward systems. A family of time-varying state feedbacks that globally, uniformly, asymptotically and locally exponentially stabilize trajectories which are not necessarily periodic functions of time is exhibited. The control design is based on the construction of a strict Lyapunov function.
