In order to improve the tracking performance of the conventional template matching method, a novel template matching method is proposed. The round template is used to ensure the rotation invariance of the method. The differential image can be got according to the original image in the polar coordinate system. The matching value is composed of the grey matching value and the differential matching value. The differential information contains the detail information of the template, which can enhance the accuracy of recognition. The gradient search is used to reduce the matching times, which can ensure the real time of the tracking system. Simulation results show that the template matching method proposed in this paper has better recognition and tracking performances than the conventional method.

The TCP congestion control plus RED queue management can be modeled as a discrete-time dynamical system, which can create complex bifurcating and chaotic behavior. Based on the model, we propose a time-dependent delayed feedback control method for controlling chaos in Internet congestion control system, and an adaptive parameter-tuning algorithms are proposed. Numerical examples show that the average queue length in the buffer of the router can be stabilized at the fixed point in the originally system.

For scaled MOSFET devices, normal operation of devices is seriously affected due to static gate tunneling leakage currents with ultra-thin gate oxide of MOSFET, and the novel MOSFET devices based on strained Si are similar to bulk Si devices in the effects. To illustrate the impacts of gate leakage current on performances of novel strained Si devices, a theoretical gate tunneling currents predicting model by integral approach following the analyses of quasi-two-dimension surface potential is presented in this paper, and on the basis of theoretical model, performances of NMOSFET devices were quantitatively studied in detail using ISE simulator including different gate voltage and gate oxide thickness. The experiments show that simulation results well agree with theoretical analysis, and the theory and experimental data will contribute to future VLSI circuit design.

In this paper, the problems of finite-time stability for both discrete-time and continuous-time switched linear systems are studied. Largest region function strategy is adopted to design the switching logic, i.e., state-dependent switching rule, which is different from the existing approach that is based on time-dependent switching strategy. Some sufficient conditions are provided for finite-time stability of both continuous-time and discrete-time switched system. Finally, an example is given to verify the efficiency of the proposed method.

In order to save communication consumption in the wireless nodes of networked control systems, this paper investigates the stabilization problem of an event-triggered constrained model predictive control. A state-feedback predictive control law is designed by solving an infinite horizon performance objective and an event-triggered condition involving the norm of a measurement error is derived based on input-to-state stability. Under the proposed mechanism, the measurements are sent by wireless network and the predictive control optimization is implemented only when the triggering conditions are satisfied. This approach not only can alleviate the energy consumption but also achieves the desired control performance and constraints satisfaction. Finally, an example is given to illustrate the effectiveness of the proposed results.

In this paper, we firstly introduce the path analysis of tracking robot, and then introduce the advantages of immune genetic algorithm (IGA). Thirdly, we combine immune genetic algorithm and OTSU threshold method to segment path of tracking robot. Because of the nonlinear solving process of immune genetic algorithm, for each chromosome, the solution of fitness function is separated. And the genetic algorithm is independent of each other, which is suitable for parallel computing and satisfy real time requirements. So OTSU combined with immune genetic algorithm not only improve the segmentation performance, but also enhance the computing speed of the algorithm. At last, the experiment results demonstrate the effectiveness of the algorithm.

In this article, a new systematic synthesis method is proposed to design a full state feedback gain-scheduling controller for Takagi-Sugeno (T-S) fuzzy plants. Both the stability and H∞ performance of the closed-loop system are considered. More specifically, by using the information that the degree of membership function is constrained within the interval [0, 1], the T-S fuzzy plant is transformed into the form of linear fractional transformation (LFT). Within the framework of LFT, the problem of stability and H∞ performance for the T-S fuzzy system can be reformulated into a convex optimization problem which can be approached by solving a set of linear matrix inequalities. A numerical example is provided to illustrate the effectiveness of the proposed method.

This paper is concerned with the finite-time stabilization for a class of linear systems subject to actuator fault using limited information. A sufficient condition is derived which reveals the relationship among the sampling period, the norm of the transition matrix of the open-loop system over one sampling period, the input matrix, the feedback gain and the vertex set of the actuator fault to achieve finite-time stability of the closed-loop systems. An example is given to illustrate the theoretical result.

This paper investigates the dynamical consensus problem of second-order multi-agent systems subject to Markov jumping delays. In this study, agents not only collaborate but also compete with each other, which is ubiquitous in real-world scenarios. Antagonistic interactions of the agents are considered, and modeled as negative weights on the communication graph. We first derive sufficient conditions for consensus in terms of matrix inequalities. Thereafter, a cone complementarity linearization (CCL) based algorithm is proposed for the delay-dependent controller design. The method's framework is formulated in sampled-data settings, to be more realistic and applicable. A numerical example is provided to illustrate the effectiveness of the proposed approach.

Cloud computing is becoming an important and popular platform of service computing for supporting on-demand service sharing in the large-scale distributed systems. One of the difficult challenges in cloud computing is how to deliver the reliable web service composition over unreliable web services around the world. To improve the automated diagnosis capability for service composition in cloud, we present diagnosis architecture and a log-based diagnosis method. By decoupling diagnosis service to share diagnosis resources, our diagnosis architecture could select an optimal diagnosis service according to the faulty type. By converting the successful activity execution logs into the diagnosis model, our diagnosis method can identify the faulty activities based on the differences between correct and observation execution traces. Case study shows that our method is effective in diagnosing service faults in cloud.
