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.

Ground test platform for attitude and orbit control system of small satellite is designed. Hardware interfaces between the real sensors/actuators and the onboard computer is simulated. Satellite dynamic and space environment is calculated in order to form a close-loop control system. Finally, the ground test system is validated by comparing the simulation result and in-orbit flying data.

Protein is the primary element of organism and takes part in almost all the biological processes such as metabolism and neurological regulation. Generally, proteins are interacting with each other while they exert biological role in vivo. The exploration upon protein-protein interactions (PPIs) of the specific biological process could provide valuable information to the study of the relevant field. In this paper, we focus on the collection of proteins participated in glucosinolate biosynthesis, and build 4 decision tree models to predict PPIs involved in glucosinolate biosynthesis. Information of domain-domain interactions (DDIs) is introduced in constructing feature vectors, and the interactive or non-interactive relationship between two proteins is represented by a pair of symmetrical feature vectors. 4 domain-based decision tree models are constructed and trained by the samples with 1:1, 1:2, 1:3, 1:4 positive-negative ratio respectively. 5-fold cross-validation and a standalone external test are used in order to trace the best performed model. The proposed method is effective which is demonstrated by the higher specificity, sensitivity and high attribute usage while training decision trees. We use the intersection of the best two prediction results to validate and explore PPIs based on the proteins participated in glucosinolate biosynthesis, and finally a comprehensive PPI network is drawn according to the prediction result.

The integrated guidance and control (IGC) technology of aircraft has been developing for more than 30 years, and it mainly focused on the research in single plane. Due to the exigent requirement on the three-dimensional IGC technology in current researches, the mathematical modeling in three-dimensional space is considered and analyzed in order to solve the primary problem during the design period of three-dimensional IGC. The three-dimensional guidance model of line-of-sight (LOS) and dynamics model of aircraft are respectively established, and then they are cooperatively united as an original state-space model. Based on some feasible simplifications, the original model is further transformed into a simplified state-space model with strict feedback form, which is propitious for the design of IGC scheme. The proposed state-space model can be directly applied to explore the advanced three-dimensional IGC approaches for unpowered sliding-to-turn (STT) aircraft with fixed target. Moreover, it also possesses higher application value.

In this paper, a robust L2-L∞ filter design method is presented for a class of continuous-time uncertain nonlinear systems of which the output equations contain the time-varying delay and the saturation items while the state equations contain the time-varying delay items. The memoryless sector region method is utilized to deal with the saturation, and the nonlinearity is subjected to the Lipschitz condition. A delay-dependent Lyapunov-Krasovskii functional(LKF) approach is presented to guarantee that the filtering error system is asymptotically stable and satisfies the L2-L∞ performance constraint. An illustrative example is used to elucidate the efficacy of the proposed approach.

As is known to all that more and more sub-health problems have been induced by weight concerns. Due to the universality and the popularity of Android Smart Phone in the domestic and foreign markets, it is possible for us to develop a real-time weight management APP software based on Android Smart phones. Working out a kind of smart insole with a wireless communication module is also necessary for the success of data transmission and data processing through the sensor in the insoles. Such a system can identify the current state of bodies' weight and sitting posture according to the plantar pressure station and will remind the users to stand up and move around to avoid a long-term sitting. It has been pointed out that this kind of system has its own profound and practical significance for the application of Smart phones in the health management.

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.

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.
