Control by Interconnection :

An Alternative Paradigm to the Signal
-
Processing Viewpoint



Abstract:
The motivation of the interconnection viewpoint in co
ntrol stems from the simple

observation that classical system theory thinking is unsuitable to deal on an appropriately

general
level with the basic tenets at which systems theory aims: the modeling, analysis and

synthesis of
open and of interconnected sys
tems that exchange mass, energy or information with

their
environment. Viewing (dynamic) relations in terms of inputs and outputs, and viewing

interconnection as input
-
to
-
output assignment, as signal transmission from one subsystem to

another, invariably i
ntroduces a structure and a mechanism that is not part of the physics. It

is
appropriate in signal processing and in sensor
-
output
-
to
-
actuator
-
input feedback control, but

it is
severely limited as a framework for dealing with interconnected systems.

The pr
imary purpose of this talk is to question the use of the input
-
output framework for

control systems design. We show throughout the use of many modern physical examples that

the
control by interconnection is more suitable, and some times the only, approach
to address

these
problems. The examples that we study include: walking robots, bilateral teleoperators,

power
factor compensation and over

voltage sup
p
ression in long cable interconnections.

Model
ing of HIV Infection: Vaccine Readiness, Drug Effectiveness

/

Therapeutical
Failures and Immune Prognosis



Abstract:

A review of mathematical models for the pathogenesi
s of HIV is

presented. Model
identifiability and identification techniques

are applied using the biomedical model and clinical
data.

Identifiability analysis aids in the determination of measured

values and measurement

frequency. Parameter identification m
ethods are chosen and developed for sparse and rough
samples. Results are reported on two case studies: vaccine readiness in Southern Africa, drug
effectiveness and therapy failures on existing patients in France. Ongoing research programmes
and future opp
ortunities are considered.

Adaptive Decoupling Control of Non
-
linear Multivariable


Systems with Dynamic State Feedback


Abstract:

It is known that the linear multivariable system is decouplable by the stat
ic state
feedback if and only if its interactor is a diagonal matrix. When the system does not have a diagonal
interactor, it is always possible to design the precompensator such that the total system has a diagonal
interactor. In this paper, we apply this

technique to nonlinear multivariable systems with unknown
parameters whose interacotors are not diagonal. First, a precompensator for a diagonal interactor is
designed in the generic sense so that decoupled output error equations are obtained. Then, this
extended system can be decoupled adaptively by using MRACS technique.

Abstract:

Based on the essence of self
-
organized criticality and optimal power flow, this paper
develops a novel model to study the cascading failures and blackouts in power systems, which
avoids the sh
ortcomings of existing blackout models. The proposed model contains two dynamics,
one is the fast dynamics which simulates the serial blackouts in power system, the other is the
slow dynamics which reflects the growth of the power system. In addition, this

model has voltage
steady stability analysis function and can reveal critical characteristics from reactive power and
voltage viewpoint. Simulations in IEEE
-
30

bus system with the proposed model show that, the
processing of the cascading and blackout can b
e captured by the fast dynamics, together with the
self
-
organized criticality property of fast dynamic respect to the micro scale. Besides, the macro
scale of self
-
organized criticality of power system can be revealed from the viewpoint of ratio of
total l
oad demand to the total network capability. Furthermore, the voltage steady stability
criticality status could be indicated from the minimum
magnitude of
eigenvalue

and the minimum
voltage steady stability margin
s
.

Finally, this work has verified that impr
oving the transmission
ability of network could effectively prevent blackout and reduce its risk.

Stability Analysis of Internet Congestion Control Systems



Abstract:

This lecture presents some preliminary results on the stability analysis of network
congestion control systems.

Due to
the difficulty of handling the so
-
called queue nonlinearity,

the queue part was usually discarded in the previous work.

In this talk, we take into account the
affect of the queue in

Transmission Control Protocol/Active Queue Management (TCP/AQM)
systems
and show how such internet congestion control systems can be formulated as switched
time
-
delay systems. A Lyapunov
-
Krasovskii

based approach is then developed for the stability
analysis of the

switched time
-
delay system under P and/or PI controllers.
