	1. Composite PDE Boundary Control of Flexible Manipulator Using Singular Perturbation Approach
	Liu Zhijie,Liujin Kun
	Information Science and System Science 24 May 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, a new composite boundary controller for flexible manipulator is presented based on the partial differential equation (PDE) model. A key contribution of this paper is the introduction of singular perturbation approach to the PDE dynamic model of flexible manipulator, which results in two simpler subsystems-slow subsystem and fast subsystem. Considering the characteristics of flexible manipulators, a composite controller for the full model is proposed, which includes a position controller for the slow subsystem and a direct feedback controller for the fast subsystem to suppress the vibration. Simulation results demonstrate the effectiveness of the proposed controller.

	Abstract:In dense small cell networks, the coverage of a typical cell is small and handover is expected to happen frequently when user moves. Thus a two stage neighboring cell list (NCL) selection (TSNS) algorithm is proposed to improve handover performance. In the first stage, TSNS updates cell specific preferences of neighboring cells based on the load, signal quality and resource utilization of the target cells. In the second stage, user specific preference is calculated considering the received signal quality, surviving time and moving direction of user. Cell specific and cell user specific preferences are merged to construct the resultant NCL. Compared with existing methods which adopt the same NCL for all users in a cell, the novelty of TSNS is that different users can have different NCLs. Simulation results prove that TSNS can yield short NCL list while ensuring good handover performance.

	Abstract:Complex network is a useful tool to study and analyze the real world networks. However, the growing number of links and nodes brings a challenge for us to analyze the complex network. How to improve the efficiency of extracting backbone has gradually been in a hot research. In this paper, we firstly review some methods of extracting backbone of complex network, and then we put forward an extracting backbone model which is based on information diffusion. Information diffusion has become a focus recently, and the mass information from internet provides data support to study the information diffusion among network. The first step of our model is to identify the critical nodes which will be the initial ones in the information diffusion model, so the information will spread from those nodes to the remainders. During the simulation, those links which play a leading role during the diffusion will be regarded as the important ones to construct the backbone of complex network.

	Abstract:The vehicular ad hoc networks(VANETs) presents the uneven node density, fast moving speed,dynamic topology change etc.In order to improve the reliability of VANETs in information broadcasting, and reduce the redundancy of multi-hop broadcast, a protocol based on the clustering position-competition of vehicular ad hoc networks is proposed. Furthermore the concept of connectivity-stability is introduced.In the paper, The road is divided into segment model and intersection model.The cluster head and the optimal nodes in the cluster are chose as a radio relay nodes, which reduces the broadcast redundancy and improves the broadcast efficiency.At the same time, for the isolated nodes in the network ,carry-forwarding method is taken ,which improves the broadcast reliability in sparse areas and in "hole" areas.Finally, we use the NS2 simulation tool to.The simulation results show that the proposed routing protocol has a better comprehensive performance in delivery success rate, average broadcast time delay and the broadcast overhead.

	5. Density Clustering Pruning Method Based on Reconstructed Support Vectors for Sparse LS-SVM

	Abstract:In least squares support vector machine (LSSVM), nonlinear function estimation is done by solving a linear set of equations instead of solving a quadratic programming problem, and a nonsparse solution is obtained. Several sparse algorithms have been developed to obtain reduced support vectors to improve the generalization performance of LSSVM. However, all of them iteratively look for support vectors in training datasets, which may are not the most superior choice for building the function model. In this paper, we propose a method of reconstructed support vectors based on the training datasets. The support vectors reconstructed are near the hyper plane of target function and uniformly distributed, which have more contribution to target function. In addition, the method we proposed converges at a faster rate than those iterative algorithms, because one-step selecting strategy is adapted without repeated training. To show the efficacy and feasibility of our proposed algorithm, some comparing experiments are conducted, which are all favorable for our viewpoints. That is, the method we proposed needs less number of support vectors to reach the almost same generalization performance, most important, which has the better robustness and accuracy prediction for the real operating mode.

	Abstract:With more and more mobile devices are connected into the network, the mobile network presents the following features: intermittent connectivity is frequent and mobile nodes can communicate with each other even if a route connecting them did not previously exist. So the mobile opportunistic networks emerged. The communications in mobile opportunistic networks take place on the establishment of opportunistic contacts among mobile nodes, without availability of end-to-end message routing paths. To ensure source nodes connect with destination quickly and send message successfully in the mobile opportunistic networks, we studied six different routing protocols for transmitting message in the mobile opportunistic networks and took analysis about their advantages and disadvantages.

	8. Robust observer for a class of linear system with matched uncertainty based on LMI
	CHEN Fengxiang,LIU Lin,SU Zhou,ZHANG Tong
	Information Science and System Science 16 July 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, a novel framework of robust observer for linear system with parametric uncertain state matrix matched with output matrix is introduced. The scheme is derived by including an extra term to the feedback gain, and the term is obtained by the analysis of the Lyapunov stability theory and LMI (Linear Matrix Inequality). The proposed observer is less conservative and thus lead to a low gain matrix based on the novel framework. Finally, the effectiveness of the proposed method is validated by the numerical simulations on Matlab environment.

	Abstract:This paper studies H-/H∞ control for MIMO singularly perturbed system(SPS) in finite frequency ranges. The sufficient conditions for the existence of an H-/H∞ sub-optimal controller are derived based on generalized KYP lemma. Moreover, the controller is also singularly perturbed. It is further shown that this controller is obtained through designing its fast and slow parts, and then the composite controller is established. The effectiveness of the proposed method is demonstrated through comparing with traditional H∞ design method.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A robust non-fragile H∞ control problems for neutral stochastic hybrid systems with time-varying delay are studied in this paper. Firstly, a delay-dependent stochastic Markov jumping bounded real lemma is presented in terms of linear matrix inequalities (LMIs). Secondly, based on the bounded real lemma, for the additive controller uncertainties, delay-dependent sufficient conditions for the solvability of non-fragile H∞ control for neutral stochastic hybrid systems with time-varying delay are derived by taking a Lyapunov-Krasovskii functional and its derivative. The desired state feedback controller can be developed by solving some certain LMIs. At last, a numerical example is given to show the validity of the obtained results and the effectiveness of the proposed method.
