Wheel skidding or spinning is dangerous for driving vehicles, and compared to conventional vehicles, electric vehicles are more easily to slip during driving on slippery road. In this paper, a novel traction control method based on wheel-slip control is proposed to improve the safety and stability of electric vehicles. Considering the high nonlinearity and uncertainties of the traction system, this paper takes use of the feedback linearization methodology to design a nonlinear controller to achieve the tracking control for wheel slip. Meanwhile, to enhance the robustness of the controller, a integral action is introduced. As the controlled variable, the desired value of the wheel slip is required in the traction control system, this paper adopts the so-called Burckhardt's model to make online calculation for it. In order to demonstrate the effectiveness of the proposed method, simulations were conducted in different road conditions, and all the simulation results showed that the wheel-slip controller could produce a fairly good control performance.

Resolvers are rugged absolute position transducers which are widely used in various servo systems. The main shortcomings of resolvers are their nonlinear output signals, and therefore additional process is needed to obtain the linear angular signal. This paper presents a new resolver to digital converter (RDC) design method based on the extended state observer (ESO) with the advantages of noise insensitivity and higher tracking accuracy. An alternative demodulation strategy is also suggested where the output of resolver is sampled at two critical points. Such a treatment can realize demodulate resolver's output more accurately. Finally, simulation and experiment results are given with respect to a full FPGA digital system.

This paper is concerned with the problem of quantized H∞ filtering for a class of continuous-time Markovian jump linear systems with defective mode information. By virtue of a mode-dependent logarithmic quantizer, the measurement output of the plant is quantized, and the defective mode information in the Markov stochastic process simultaneously involves the exactly known, partially unknown and polytopic-type uncertain transition rates. By fully exploring the properties of transition rate matrices, together with the convexification of uncertain domains, a new quantized H∞ performance analysis criterion is first derived and then the filter synthesis is developed. It is shown that via a linearisation procedure, a unified framework can be developed such that both the full-order and reduced-order filters can be obtained by solving a set of linear matrix inequalities. Finally, an illustrative example is given to show the effectiveness of the proposed design method.

The method of designing the H∞ three-delay controllers for systems with time delay is investigated in this paper. The advantages of the controllers based on the delay modules lie in that it is easy to implement and it can be implemented in the occasions that ordinary controllers cannot be implemented. The three delay modules introduced into the controller is to improve the performance of the controlled system. Based on the complementary sensitivity function, the parameters of the three-delay controller are optimized with H∞ performance. Then, the problem of finding the set of the H∞ three-delay control parameters satisfying the certain H∞ performance is converted to the problem of stabilizing the quasi-polynomials which can be solved by using the D-composition method. Finally, the set of the three-delay control parameters is derived by finding the intersection of stable region and H∞ region. The simulation results verify the effectiveness of the proposed method.

This article proposes an efficient and reliable communication mechanism of mobile Agent based on the current communication mechanism of mobile Agent to combine mobile Agent name resolution mechanism with message transfer mechanism. The communication component of the domain server and mobile Agent system are combined to realize the mobile Agent communication. The message processing uses the message storage and transfer mechanism based on the e-mail and the buffer pool processing, message transfer status and offline transfer in mobile Agent. In the Agent message and email migration we need check whether the message is timeout or not and its priority status. When deleting overtime message, give priority to the implementation of high priority message. This mechanism improves the communication efficiency of mobile Agent, solves the communication failure of mobile Agent problems, ensure the stability of the system and realize a distributed communication mechanism.

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.

Because it is hard to depict real world traces, researchers proposed some mobility models in the study of mobile ad-hoc networks. It is aware recently that some mobility models will lead to non-uniform node distribution, which decreases the credibility and validity of simulations. Many researchers reconsider the node distribution characteristic for random waypoint model and have gotten some valuable and quantitative results. But similar investigations on the random direction model (RD) in square region are still missing. We presented a detailed analysis to the probability behavior of RD model in square region. Numerical solutions of node distribution are obtained. It shows that node distribution probability is higher and higher as its location varies by the sequence of center, border, and corner. It is to say that the stationary node distribution of random direction model is non-uniform.
