International Conference on Fuzzy Systems and Knowledge Discovery (FSKD)

A new blind equalization scheme is proposed based on concurrent modified square contour algorithm (MSCA) and a novel soft decision-directed (SDD) adaptation. This proposed blind equalization scheme (MSCA+SDD) may be viewed as operating a MSCA equalizer and a SDD equalizer concurrently. The MSCA term provides good steady- state equalization performance and global convergence, moving the equalizer weight vector on the correct direction; after the equalizer enters the fine local convergence region, the SDD term helps to accelerate convergence. The performance is measured for realistic microwave channel models and the simulation results demonstrate that both the MSCA+SDD and the MSCA have the same steady-state equalization performance, but the former has a faster convergence speed.

For quaternion model of two-dimensional harmonics, the singular values decomposition (SVD) method of quaternion matrix presented to estimate frequency pairs of two- dimensional harmonics. This method may estimate the number of signals by singular values. The left and right singular vectors of quaternion matrix were used to estimate frequency pairs. This method needs lesser data and data matrix is very simple. Simulations show that this method can decrease computation burden effectively than other methods.

A dynamic scheduling strategy based on network running situation is proposed to allocate network bandwidth by adjusting the sample periods of control systems sharing CAN resource in the networked control systems. Then the NCS is a vary-sample period system which is modeled as a class of discrete switched systems when network-induced delay and data-packet dropout exist. Based on the model, the approach of robust controller design is studied. Finally, a group of simulations validate the effectiveness of the control and scheduling co-design method.

This paper considers the general filtering problem for a distinct class of two-dimensional (2-D) discrete linear systems, i.e. information propagation in two independent directions, known as discrete linear repetitive processes which are of both system-theoretic and applications interest. In particular, new results on the design of filters with guaranteed levels of performance are developed. These take the form of algorithms for the design of an ∞ and 2-∞ dynamic output feedback filter which guarantees that the resulting filtering error process is stable and has prescribed disturbance attenuation performance as measured by ∞ and 2- ∞ norms. © 2007 IEEE.

In the last few years we have observed an explosive growth of multimedia computing, communication and applications. Information technology (IT) has a great effect in our everyday life and is transforming the way people live, work, and interact with each other, and is impacting the way businesses, government services, education, entertainment, and medical-care are operating. In this research, we propose and develop a remote medical-care system for supporting nurses, care managers and care helpers during their work. The proposed system has three functions: a multi-point communication function using video images and voice, vital signs data auto-uploading and referring function, and a drip infusion monitoring function. In this paper, we present the proposed remote medical-care support system

2007 International Power engineering Conference (IPEC2007), vol.2

作者： Saravuth Pothiya Issarachai Ngamroo Waree Kongprawechnon School of communication Instrumentation&Control Sirindhorn International Institute of Technology Thammasat University Pathum Thani Thailand Electrical Engineering Department Faculty of Engineering King Mongkut's Institute of Technology Ladkrabang Bangkok Thailand

This paper proposes a new optimization approach of a Fuzzy Logic based-Proportional-Integral-Derivative (FLPID) controller by the Multiple Tabu Search (MTS) algorithm for Automatic Generation control (AGC) including Superconducting Magnetic Energy Storage (SMES) units. Conventionally, the membership functions and control rules of fuzzy logic control are obtained by trial and error method or experiences of designers. To overcome this problem, the MTS is applied to simultaneously tune PID gains, membership functions and control rules of FLPID controller to minimize frequency deviations of the system against load disturbances. The MTS algorithm introduces additional techniques for improvement of search process such as initialization, adaptive search, multiple searches, crossover and restarting process. Simulation results explicitly show that the performance of the proposed optimum FLPID controller is superior to the conventional PID controller and the non-optimum FLPID controller in terms of the overshoot, settling time and robustness against variations of system parameters.

Robust fault detection for discrete-time Markovian jump systems with mode-dependent time-delays

控制理论与应用（英文版） 2007年第2期5卷 139-144页

作者： Hongru WANG Changhong WANG Shaqshuai MOU Huijun GAO School of Information ＆ Communication Engineering Harbin Engineering University Harbin Heilongjiang 150001 China Space Control and Inertial Technology Research Center Harbin Institute of Technology Harbin Heilongjiang 150001 China Department of Electrical and Computer Engineering The University of Alberta Edmonton Alberta T6G 2V4 Canada

This paper investigates a fault detection problem for a class of discrete-time Markovian jump systems with norm-bounded uncertainties and mode-dependent time-delays. Attention is focused on constructing the residual generator based on the filter of which its parameters matrices are dependent on the system mode, that is, the fault detection filter is a Markovian jump system as well. The design of fault detection filter is reduced to H-infinity filtering problem by using H-infinity control theory, which can guarantee the difference between the residual and the fault （or, more generally weighted fault） as small as possible in the context of enhancing the robustness of residual to modeling errors, control inputs and unknown inputs. Sufficient condition for the existence of the above filters is established by means of linear matrix inequalities, which can be readily solved by using standard numerical software. A numerical example is given to illustrate the feasibility of the proposed method.
