In this paper, the problem of observer-based robust fault detection is studied for T-S fuzzy systems. A T-S model described fuzzy observer is considered as a fault detection filter to generate residual. The problem of fault detection is formulated into a model-matching problem so that the influence of uncertainty and disturbance is minimized to increase the robustness of residual to unknown inputs,...

The problem of the robust stability and non-fragile control of closed-loop system is studied for the system with structured uncertainties both in plant and controller. Non-fragile robust stability and performance sensitivity of the closed-loop system with left coprime factor perturbations and right coprime factor perturbations are investigated respectively, and the sufficient conditions are given...
The discovery of underlying community structures is a common challenge in the analysis of network data. This paper presents a novel algorithm which gives consideration to both modularity and robustness of the clustering. It's based on SCAN which can detect more details about clusters, hubs and outliers. In order to demonstrate the advantages of this new algorithm in coordinating networks scale with...
The flow field surrounding an underwater vehicle will change due to the influence from seabed terrains, when it navigates near seabed. The hydrodynamic coefficients of the underwater vehicle will change, and then produce a force and pitch moment, which could pull the underwater vehicle to the seabed. So it's very important for the safety of underwater vehicles while navigating near seabed to predict...

IP Multimedia Subsystem (IMS) not only inherits the telecom advantages, but also brings several disadvantages, such as poor scalability, single point of failure, etc. Peer-to-Peer (P2P) network has the advantage of scalability and robustness, but there are some difficulties in the peer management and route optimization. By reusing the mechanism of signaling control and media negotiation in IMS, P2P...
A novel model about the local-world linear expanding evolution of wireless sensor networks(WSNs) has been put forward in the basis of the classic BA scale-free model. The four types of internal evolving behaviors in wireless sensor networks are reflected in the dynamic process of the model. With the application of continuous field theory, the characteristics of network nodes' degree distribution are...
It is an efficient way to eliminate “crosstalk” signals in spatial audio reproduction by using crosstalk cancellation system (CSS). It is well-known that the problem of CCS is that it is quite sensitive to the listener's head movement. In this paper, we propose a global optimal algorithm based the Maximin criterion to provide increased robustness for the head movement. Simulation results demonstrate...
