Channel imperfection effects on THP performance in a slowly time varying MIMO channels
2010 Edition, June 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Tomlinson-Harashima Precoding (THP) is an attractive solution for a scenario where the transmission system employs multiple transmit antenna and multiple users with single antenna at the receiver. In spite of THP's good performance, it is very sensitive to erroneous...

Slowly varying wave drifting force on a very large floating structure in short crested waves
2000 Edition, Volume 1, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Hydroelastic responses of very large floating structures (VLFS) have been studied activity in Japan. Most targets of them are hydroelastic behavior and an estimation method of linear hydrodynamic forces for the prediction of it. However a design of mooring system is very important...

Stability analysis on continuous neural networks with slowly synapse-varying structure
1992 Edition, Volume 1, January 1, 1992 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A neural network with slowly synapse-varying structure is a nonlinear time-varying system. A linearization method for analyzing dynamics of such networks is given, their stability is investigated, and some results that are instructive for developing...

Slowly varying bias of magnetometer based on orbit geometry
2004 Edition, Volume 40, July 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A new method is proposed to correct the induced magnetic disturbance using a set of measured magnetic field data from the three-axis-magnetometer on orbit. The magnetic field correction is based on the orbit geometry and its algorithm excludes the geomagnetic field model...

Persistent disturbance attenuation properties for networked control systems
2004 Edition, Volume 1, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, both the asymptotic stability and l/sup /spl infin// persistent disturbance attenuation issues are investigated for a class of networked control systems (NCSs) under bounded uncertain access delay and packet dropout effects. The basic idea is...

Stability analysis and synthesis for slowly time varying systems based on non-common Lyapunov matrices
2003 Edition, September 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recently, new stability analysis and controller synthesis methods based on non-common Lyapunov matrices are proposed. In this paper, we give another simple and easy proof for them using redundant descriptor form. Furthermore, we propose a sufficient condition for stability of...

Optimal rejection of persistent and bounded disturbances: continuity properties and adaptation
1990 Edition, Volume 35, June 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Continuity properties of the problem of optimal rejection of bounded persistent disturbances, otherwise known as l/sup 1/-optimal control, are furnished for discrete-time, single-input, single-output systems. It is shown that for any plant with no zeros on the...

Worst-case performance and stability of multirate sampled-data systems with nonsynchronous decentralized controllers
1997 Edition, Volume 1, January 1, 1997 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper focuses on multi-rate sampled-data control of large-scale systems with nonsynchronous decentralized controllers whose sampler-and-hold elements in different stations update their state independently of each other. Phases of discrete-time events in...

On optimization with competing performance criteria
1995 Edition, Volume 4, January 1, 1995 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In control system design one typically optimizes a performance function over the space of frequency response functions of all designable controllers. In H/sup /spl infin// control one typically optimizes a sup norm type of performance function...

Bounds on the Distortion for Distributed Sensing of Slowly-Varying Random Fields
2007 Edition, November 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We consider a wireless sensor network deployed in an area to measure the realization of a finite multi-dimensional, slowly time-varying physical random field. Each sensor observes one noisy realization of the field, maps it linearly into a signal with a signature and...
