Based on a creative sliding mode prediction model, a novel sliding mode observer (SMO) design method for discrete-time nonlinear uncertain systems is presented in this paper. By combining feedback correction approach, the observer states can close to system states as exactly as possible, and chattering is eliminate simultaneously. Because of the employing of receding horizon optimization technique, the observer compensatory term can be optimized continuously and on-line. The proposed method guarantees the SMO is robustly stable. The satisfying properties of the SMO are verified by a numerical example.

The paper completed all the correction of constellation error and receiver channel error. It was brought forward a comprehensive scheme for position error correction. The experiment platform was based on Superstar II GPS receiver and Matlab. It mainly corrected the position error such as satellite clock error, ionospheric error, tropospheric error, the earth rotation effect etc. Moreover, ionospheric delay error was corrected for about 14 m by Klobuchar model; tropospheric error was corrected for the average value of 4.05 m by the altitude angle module and so on. Especially, the satellite clock error was corrected for 3.1 m related to IGS by empirical formula. The user clock error is the max error with magnitude of 104~105 s to affect position result. Finally, these methods improved the positioning precision to 17 m. The result of experiment has proved the validity of these correcting methods, accumulating much experience for the next investigation.
完成了星座误差和接收机信道误差的全部校正。提出了一种综合的位置误差校正方案。实验平台基于Superstar II GPS接收机和Matlab。主要对卫星时钟误差、电离层误差、对流层误差、地球自转效应等位置误差进行校正。利用Klobuchar模型对电离层延迟误差进行了约14 m的修正;对流层误差经高度角模等校正为平均值4.05 m。利用经验公式对与IGS相关的3.1 m卫星时钟误差进行了修正。用户时钟误差是影响定位结果的最大误差，其量级为104~105秒。最后，这些方法将定位精度提高到17 m。实验结果证明了这些校正方法的有效性，为下一步的研究积累了经验。

The use of continuous-time hidden Markov models for network protocol and application performance evaluation has been validated to simulate network environments. In this paper, we develop a better algorithm to infer the continuous-time hidden Markov model from a series of end-to-end delay and loss observation of probing packets. We prove the algorithm's feasibility by theory deduction and realize numerable validation by comparing the probability of the observed sequence produced by the model inferred by different methods. The algorithm complexity is lower.

Fast fuzzy support vector machines (FFSVMs) based on the convex hulls are proposed in this paper. Firstly, the convex hull of each class data is generated by using the quick hull algorithm, and the data points lying inside the convex hull are not important to form FSVMs and then discarded. Secondly, the reduced training set consisting of the convex points is used to train the FFSVMs. Thirdly, the benchmark two-class problems and multi-class problems datasets are used to test the effectiveness and validness of FFSVMs. The experiment results indicate that FFSVMs not only reduce the training set but also achieve the same or better performance compared with the traditional FSVMs.
