A dynamic error-feedback controller is presented for the synchronized
output regulation of heterogenous linear networked systems, where only
the leader nodes have the information of the regulated errors while
the remaining follower nodes have the information of the relative output
errors with respect to their in-neighboring nodes. By using the
small-gain theorem, the sufficient criterion is developed for more general
networks to judge whether the synchronized output regulation can be
achieved under the designed controller. This criterion can be regarded
as to to impose an additional H ∞ constraint on the output regulation
problem. The synthesis problem is addressed in terms of linear matrix
inequality. The efficacy of the analytic results is illustrated by simulation
examples.

Dynamic Configuration of Service based Processes in Cloud Computing

To guarantee the successful execution of service based process, one
important requirement is QoS-driven dynamic configuration of candidate
services. The existing methods don’t simultaneously consider
the temporal constraints from users, uncertain QoS information of candidate
services and dynamic re-planning on run-time. In this paper,
we propose a novel approach to dynamically configure the services for
service based process under both uncertain QoS information and temporal
constraints. Our approach can efficiently select the appropriate
services for multiple service based process in practical business environment.
Furthermore, if some temporal constraint is violated in execution,
we provide solutions to re-plan them so that the violations can be
addressed on run-time. The usability of our approach is validated on a
practical example.

In Complex Adaptive Systems, agents co-adapt to each other through
interaction. A typical example is game: players learn and adapt to the
opponent through game playing. This paper studies the adaptive characteristic
of co-adaptation through a combinatorial game “Five-in-arow”.
The computer simulations show that a high-level player will win
more if she knows the opponent’s next move, but a low-level player will
lose more if she knows the opponent’s next move. To explore the reason
of this phenomenon, an abstract theoretical model is built based on
a full, k-ary game tree which also shows the above phenomenon. Some
analysis and discussion are carried out based on this model. This result
indicates that identification of the opponent only is not enough; she
has to improve herself as well.

Complex systems with components or subsystems having game-like
relationships are probably the most complex ones that we encounter
everyday. Much progress has been made over the past half century
on differential games which are used as a tool in modeling conflicts in
the context of dynamic systems, however, almost all of the current literature
assume that both the parameters and the structure of the game
are known to the players. Since in many practical situations, the players
may have unknown parameters, which motivate us to investigate
a class of two-player zero-sum linear-quadratic stochastic differential
games in [1] with unknown parameters. In this paper, we will further
consider a class of two-player nonzero−sum linear quadratic s-
tochastic differential games, with unknown parameters to both players.
We will design adaptive strategies and prove that they will converge to
the optimal ones under

Flight test subjects have high risk and difficult to evaluate quantificationally.
A test pilot model based on distribution hypothesis verification
is proposed to obtain the test pilot’s manipulation parameter. Delay
time is selected as an example to illustrate the method. Aircraft model
and hydraulic system model is established. Failure model of hydraulic
system’s sensor and actuator malfunction, oil block and pump power
were set up and simulated by Simulink and AMESim. To improve
the precision of flight risk assessment, an improved extreme value risk
evaluation model based on nonlinearly decreasing weight particle swarm
optimization (NDW-PSO based EVT) is proposed. Dynamic simulation
from component level to aircraft level was realized by a comprehensive
virtual flight testing (VFT) framework based on AMESim, MAT-
LAB/Simulink and Flightgear cross-connect. NO.43 risky subject about
“hydraulic system malfunction”in Chinese GJB 626A-2006 was chosen
as an example. Influence of hydraulic system failure to flight safety
was analyzed and safety amelioration measures were proposed, which
illustrate the former proposed method’s validity.

Waterway management is an important tool to ensure safe smoothness
of the waterway and enhance the traffic capacity. Aimed at the incompleteness
in information resulted in safe fault triggered by limitation of
command dispatch capability, and in waterway availability lowering etc,
the paper designed and implemented a management system of main
waterway station. Based on the integration of information fusion and
adopted .NET frame, according to the hybrid architecture of B/S and
C/S, it designed the related functional modules such as data acquisition,
comprehensive management and command dispatch and so on,
and realized the waterway managemant, command dispatch, dynamic
monitoring of the vessel, vessel managemant, dispatch in maintenence
and emergency rescue etc. The basic tests of the realized system show
that it is reasonable in system design, and owns its feasibility and usability
of engineering application.
