| 1 | Energy-balanced multiple-sensor collaborative scheduling for maneuvering target tracking in wireless sensor networks显示文摘An energy-balanced multiple-sensor collaborative scheduling is proposed for maneuvering target tracking in wireless sensor networks (WSNs). According to the position of the maneuvering target, some sensor nodes in WSNs are awakened to form a sensor cluster for target tracking collaboratively. In the cluster, the cluster head node is selected to implement tracking task with changed sampling interval. The distributed interactive multiple model (IMM) filter is employed to estimate the target state. The estimation accuracy is improved by collaboration and measurement information fusion of the tasking nodes. The balanced distribution model of energy in WSNs is constructed to prolong the lifetime of the whole network. In addition, the communication energy and computation resource are saved by adaptively changed sampling intervals, and the real-time performance is satisfactory. The simulation results show that the estimation accuracy of the proposed scheme is improved compared with the nearest sensor scheduling scheme (NSSS) and adaptive sensor scheduling scheme (ASSS). Under satisfactory estimation accuracy, it has better performance in saving energy and energy balance than the dynamic collaborative scheduling scheme (DCSS). | Liu, Yonggui Xu, Bugong Feng, Linfang | 2011 | 控制理论与应用(英文版)2011，9，1： | 7 |
| 2 | H_2 /H_∞ control of networked control system with random time delays显示文摘This paper investigates the H 2 /H ∞ control problem for a class of discrete-time networked control systems with random communication time delays. Both sensor-to-controller (S-C) and controller-to-actuator (C-A) random network-induced delays are considered. Two independent Markov chains are used to model the S-C and C-A random delays. The resulting closed-loop system is a jump linear time-delay system induced by two Markov chains. Sufficient conditions for existence of H 2 /H ∞ controller are established by free-weighting matrix and stochastic Lyapunov functions. A simulation example illustrates the effectiveness of the proposed method. | QIU Li XU BuGong LI ShanBin | 2011 | Science China(Information Sciences)2011，54，12： | 5 |

| 6 | Stability criteria for linear systems with multiple time-varying delays显示文摘New delay-independent and dehy-dependent stability criteria for linear systems with multiple time-varying delaysare established by using the time-domain method. The results are derived based on a new-type stability theorem for general retarded dynamical systems and new analysis techniques developed in the author' s previous work. Unlike some results in the literature, all of the established results do not depend on the derivative of time-varying delays. Therefore, they are suitable for the case with very fast time-varying delays. In addition, some remarks are also given to exphin the obtained results and to point out the limitations of the previous results in the literature. | Bugong XU(Laboratory of Real-Time Control Through Internet and Fieldbuses, College of Automation Science and Engineering, South China University of Technology, Guangzhou Guangdong 510640, China) | 2003 | 控制理论与应用(英文版)2003，1，1： | 1 |
| 7 | Decentralized robust stabilization of discrete-time fuzzy large-scale systems with parametric uncertainties: a LMI method显示文摘Decentralized robust stabilization problem of discrete-time fuzzy large-scale systems with parametric uncertainties is considered. This uncertain fuzzy large-scale system consists of N interconnected T-S fuzzy subsystems, and the parametric uncertainties are unknown but norm-bounded. Based on Lyapunov stability theory and decentralized control theory of large-scale system, the design schema of decentralized parallel distributed compensation (DPDC) fuzzy controllers to ensure the asymptotic stability of the whole fuzzy large-scale system is proposed. The existence conditions for these controllers take the forms of LMIs. Finally a numerical simulation example is given to show the utility of the method proposed. | Zhang Yougang Xu Bugong | 2006 | Journal of Systems Engineering and Electronics2006，17，4： | 1 |

| 13 | Guaranteed cost control for discrete-time networked control systems with random Markov delays显示文摘The guaranteed cost control for a class of uncertain discrete-time networked control systems with random delays is addressed.The sensor-to-controller (S-C) and contraller-to-actuator (C-A) random network-induced delays are modeled as two Markov chains.The focus is on the design of a two-mode-dependent guaranteed cost controller,which depends on both the current S-C delay and the most recently available C-A delay.The resulting closed-loop systems are special jump linear systems.Sufficient conditions for existence of guaranteed cost controller and an upper bound of cost function are established based on stochastic Lyapunov-Krasovakii functions and linear matrix inequality (LMI) approach.A simulation example illustrates the effectiveness of the proposed method. | Li Qiu Bugong Xu Shanbin Li | 2011 | Journal of Systems Engineering and Electronics2011，22，4： | 1 |

| 17 | Novel sensor scheduling and energy-efficient quantization for tracking target in wireless sensor networks显示文摘This paper focuses on sensor scheduling and information quantization issues for target tracking in wireless sensor networks (WSNs). To reduce the energy consumption of WSNs, it is essential and effective to select the next tasking sensor and quantize the WSNs data. In existing works, sensor scheduling' goals include maximizing tracking accuracy and minimizing energy cost. In this paper, the integration of sensor scheduling and quantization technology is used to balance the tradeoff between tracking accuracy and energy consumption. The main characteristic of the proposed schemes includes a novel filtering process of scheduling scheme, and a compressed quantized algorithm for extended Kalman filter (EKF). To make the algorithms more efficient, the proposed platform employs a method of decreasing the threshold of sampling intervals to reduce the execution time of all operations. A real tracking system platform for testing the novel sensor scheduling and the quantization scheme is developed. Energy consumption and tracking accuracy of the platform under different schemes are compared finally. | Guiyun LIU Bugong XU | 2013 | 控制理论与应用(英文版)2013，11，1： | 1 |

| 19 | Node coordination mechanism based on distributed estimation and control in wireless sensor and actuator networks显示文摘Wireless sensor and actuator networks(WSANs)have a wide range of applications.To perform effective sensing and acting tasks,multiple coordination mechanisms among the nodes are required.As attempt in this direction,this paper describes collaborative estimation and control algorithms design for WSANs.First,a sensor-actuator coordination model is proposed based on distributed Kalman flter in federated confguration.This method provides the capability of fault tolerance and multi-source information fusion.On this basis,an actuator-actuator coordination model based on even-driven task allocation is introduced.Actuators utilize fused sensory information to adjust their action that incur the minimum energy cost to the system subject to the constraints that user’s preferences regarding the states of the system are approximately satisfed.Finally,according to system requirements,a distributed algorithm is proposed to solve the task allocation problem.Simulations demonstrate the effectiveness of our proposed methods. | Lei MO Bugong XU | 2013 | 控制理论与应用(英文版)2013，11，4： | 0 |
