Pinning Control and Controllability of Complex Networks

Chen, Guanrong
IEEE Life Fellow
City University of Hong Kong, China

Abstract:

We introduce the notion of pinning control and discuss the complete state controllability of networked higher-dimensional linear time-invariant dynamical systems interconnected through directed and weighted higher-dimensional communications. We show how the network topology, node-system dynamics, external control inputs, and inner interactions affect the controllability of such a complex network. We present precise necessary and sufficient conditions for the network controllability in a general topology, as well as in some special configurations such as chains and cycles with more subtitle details.     see more>>>

 

 

New Trends in Chaotic Systems and Their Real World Applications

Boubaker, Olfa

University of Carthage, Tunisia

            
Abstract:

Chaos is the property of complex systems whose behaviours are so unpredictableas to appear random, owing to great sensitivity to small changes in conditions. While most traditional sciences deal with supposedly predictableand controllable phenomena like gravity and electricity, Chaos Theory deals with nonlinear phenomena that seem impossible to predict and control, like weather, brain states and erratic flows of epidemics. Therefore, the objective of this talk is to offer a concise introduction to the many facets of chaotic systems by exploring some new proprieties related to the particular phenomenon of chaos. Some novel chaotic and hyperchaotic systems will be presented and analyzed via some relevant tools including experimental results. Recent advances in chaos synchronization will be also introduced. The main objective is to show the pivotal role of this erratic phenomenon in several fields and its potential role for real world applications.     see more>>>

 

 

Operator Based Robust Nonlinear Control and Its Application on Wireless Power Transfer System

Deng, Mingcong

Abstract:

In order to address nonlinear behaviours in real application, in this talk, operator based models are introduced, which describe the nonlinear dynamics based on fundamental physical and chemical rules. As for the compensation on the dynamics, based on the concept of Lipschitz operator and the operator based robust right coprime factorization condition, robust nonlinear control design schemes are proposed to guarantee the robust stability and desired performance of the above nonlinear dynamics. Especially, some current developments on the above approach are shown. For demonstrating the effectiveness, numerical simulations and experiments are shown by applying the above-mentioned control design to wireless power transfer system.     see more>>>

Abstract:

Benefited from technical advances in materials, mechatronics, communication, computation, control, sensors, actuators and new/smart designs, Unmanned Aerial Vehicles are gaining more and more attention and rapid development during the last a few years due to their relatively easy and cost-effective uses in various application tasks such as surveillance, sensing, search and rescue, agriculture, forest, environment, pipelines, powerlines, military and security applications. In this plenary speech, brief overall view on the challenges and latest developments on Guidance, Navigation, and Control of UAVs integrating with Remote Sensing techniques for autonomous, efficient and reliable applications to forest, powerline and environment monitoring and fires/damages/risks detection will be presented first, then some of new developments and current research works being carried out at the speaker’s group will be introduced as the second part of the presentation. In particular, new developments on Fault Detection and Diagnosis, Fault-Tolerant Control, Fault-Tolerant Cooperative Control techniques towards new modelling, identification, and control techniques for autonomous and reliable applications to the above-mentioned tasks, and the new technical developments for image-based efficient and reliable detection of fires/damages/risks based on remotely sensed signals/images from onboard UAVs will be presented.     see more>>>
