IDENTIFICATION OF SYSTEM PARAMETERS IN DISTRIBUTED PARAMETER SYSTEMS

IFAC Proceedings Volumes, 1990
The problem of identifying system parameters for time-invariant distributed parameter systems subject to unknown boundary conditions and initial conditions is investigated. An extension of the linear integral filter is made for handling partial derivatives of multi-variable functions. In the noise-free case, applying the extended linear integral filter

OBSERVERS FOR DISTRIBUTED-PARAMETER SYSTEMS

IFAC Proceedings Volumes, 1989
This paper introduces a series of problems on state estimation for parabolic systems on the basis of measurements generated by sensors in the presence of unknown but bounded disturbances. Observability issues and relations to stochastic filtering schemes for distributed processes are also discussed.

A distributed parameter system simulator

SIMULATION, 1986
A simple and easy-to-use computer simulator (TDP) t for distrib uted parameter systems is presented. The simulator is based on commercially available TWODEPEP (a partial differential equa tion solver), to which measurement and control software mod ules have been added.

Parameters for distributed system design

Journal of Parallel and Distributed Computing, 1990
Abstract This paper analyzes the architectural choices which limit a system's ability to achieve specific design goals. A “layered black box” methodology for the analysis of distributed systems is introduced which allows the easy definition and manipulation of abstract systems.

Estimation of Distributed Parameter Systems

Journal of Guidance, Control, and Dynamics, 1982
The estimation and control of large flexible space structures pose significant new control technology problems. One major problem area is the closed-loop stability of a structure that has been modeled with truncated modal dynamics. Stability problems arise due to the control design process beginning with a deficient model.

Parameter Identification Problem for a Class of Distributed Parameter Systems

IFAC Proceedings Volumes, 1983
Summary: The inverse parameter problem of the permeable law for the fracture reservoir with double porosity is of great importance in the exploitation of oil or gas. The total compressibility and permeability are the unknown geological parameters in the fluid motion equations. In this paper we discuss the inverse parameter problem from the point of the

Parameter identification of distributed parameter systems

Mathematical Biosciences, 1985
The problem of parameter identification for distributed parameter systems is placed in an abstract system-theoretic context, and necessary and sufficient conditions developed for parameter identifiability. Applications are given for parabolic partial differential equations.

Parameters for system effectiveness evaluation of distributed systems

IEEE Transactions on Computers, 1996
Summary: In a distributed computing system, the failure of one or more system components causes the degradation in its effectiveness to complete a given task as opposed to a complete network breakdown. This paper addresses the issue of degraded system effectiveness evaluation by introducing two static measures, namely, distributed program performance ...
