It is well known that a regular implementation is more generalized interconnection than a feedback interconnection in the standard setting.In this talk, we formalize simultaneous stabilization problem by using regular iomplementation and provide a condition for a pair of linear systems to be simultanous stabilization by regular implementation.

This paper presents a new concept of robust control of time delay systems with mismatches of delay and delay-free part. The model errlrs are estimated as time delay and compensated by time delay or the first-order Pade approximation. The stability conditon and the design method are presented.

Exact robust H2 performance analysis is considered for linear time-invariant systems whose coefficient matrices are polynomial functions of a single parameter.A necessary and sufficient condition is derived as a set of parameterized LMIs with a polynomial matrix variable, where an upper bound of its degree is given explicitly.Then, the parameterized LMIs are transformed exactly to parameter-independent and finite-dimensional LMIs.

This paper studies the problem of the relations between existence conditions of common quadratic and those of common infinity-norm Lyapunov functions for sets of discrete-time linear time-invariant (LTI) systems. It turns out that although the relation is an equivalent one for single stable systems, the existence condition of common infinity-norm type is strictly implied by that of common quadratic type for the set of systems.

The decentralized control system is a large scale systemin which the plant is controled by mutually independentcontrollers. In this talk, we consider the decentralizedcontrol system synthesis from the behavioral viewpoint.We attempt to extend the implementabilityand regular implementability conditions for centralized controlsysytem to the decentralized case.

Augmented Reality is a technology for displaying virtual objectsin the real world as if it really exist there. We have proposedsome interface systems such as "MagicCup" for virtual object manipulation in the real world based on augmented reality.This paper describes about usability evaluations on MagicCup.

In this paper we propose a quantitative evaluationmethod of right- or left-handedness of a person from a set of positioning, force exertion, and manipulation task in a virtual environment constructed by using haptic virtual reality technology. Merit of virtual test tasks over real tasks is that it's easier to provide a larger variety of tasks and to get more detailed data for evaluation.

Steno sign is the history of 100 years or more, and has described the conversation with paper and a pencil. The one to propose the direction where shorthand is new by proposing the system that inputs steno sign directly to the computer in this announcement. Moreover, tablet PC was used to input directly.

The wireless technologies enable data exchange between in-vehicle and out of vehicle just as telematics services. And now Java technology is proposed as the platform of in-vehicle terminal because of its platform-independence. We show the Java virtual machine with the extension API for our in-vehicle navigation system, and some telematics applications.

The smart washer can detect the bolt loosening by using the self-sensing/actuation function.Experimental results were shown about the influences of frequency characteristic for the temperature changing. This paper was discussed about the design method, due to the smart washer is not yet enough to detect high sensitively.

System-level design is the key to improve the designefficiency for embedded systems and SoCs.In system-level design, appropriate communicationinterfaces are required for flexible hardware/software partitioning and efficient functional verification.This paper presents three design levels, i.e., specification level,architecture level, and implementation level. Then, wedefine communication interfaces for the abstractionlevels.
