This paper studies a continuous linear control system with actuator and sensor faults for its guaranteed cost control and H∞ control. When the actuator and the sensor synchronize fault, in view of the actuator and the sensor performance's quality increase the quality of normal actuator and sensor under guarantee the system stabled, enables the system to have certain performance and along with increasing the normal actuator and the sensor system's performance will no less than the system with less normal actuator and sensor. The developed theory is illustrated by a simulation example, which shows the validity of the proposed method and the necessity of such a satisfactory fault-tolerant control. ©2010 IEEE.

This paper studies the problem of robust guaranteed cost control for the Markovian jump systems with time delay. The problem is to design a state feedback controller such that the closed-loop system is robustly stochastically stable and the closed-loop stochastic guaranteed cost function is not more than a specified upper bound for all admissible uncertainty and time delay. A criterion for the existence of such controller is derived based on the Lyapunov function combined with linear matrix inequalities (LMI). A parameterized characterization of the robust guaranteed cost controller is given in terms of the feasible solutions to the certain linear matrix inequalities. An example is presented to show that the result is efficient. ©2010 IEEE.

This paper is to concern the resilient guaranteed cost state feedback controller of autonomous underwater vehicles (AUVs) in vertical plane. Basing on the established dynamic model ,this paper linearizes the nonlinear model at vertical plane with the assumption that the hydrodynamic parameters of the nonlinear vehicle model are precisely known. Then we get the singular system of AUV. By using linear matrix inequality (LMI) and MATLAB technique, a resilient guaranteed cost controller is designed. In the end, simulations are given to verify the effectiveness of the proposed methods. ©2010 IEEE.

This paper is to concern the resilient guaranteed cost controller of autonomous underwater vehicles (AUVs) in vertical surface movement system. In this paper the system is a class of nonlinear singular time-delay systems with uncertainties. The uncertainties are not only in the systematic matrix but also in the controller gain. Based on linear matrix inequalities (LMIs), a resilient guaranteed cost controller is designed. In the end, through the simulation to the AUV vertical surface movement systems, the result illustrates the effectiveness of the design method. © 2010 IEEE.

Empirical mode decomposition (EMD) can adaptively decompose multicomponent signals into a finite number of simple oscillatory mode functions termed intrinsic mode functions (IMFs) through a sifting process. In this paper, a tree-structured EMD filter is designed to describe the EMD algorithm. The core element of the EMD filter is called sifting filter which depicts the EMD sifting process of extracting an IMF. As a consequence, the tree-structured EMD filter can make toward a better understanding of the EMD method.

The problem of robust stochastic stabilization and robust H ∞ control for a class of uncertain stochastic time-delay Markovian jump system with state and input delays is discussed. Based on Lyapunov-Krasovskii function, a memory-less state feedback controller is designed in order to make the closed-loop system robust stochastic stable and meet H ∞ performance for all admitted uncertainties. At the same time, a sufficient condition for this problem is given in the form of linear matrix inequalities (LMI). Finally, a numerical example shows the effectiveness of the proposed method.

The discovery of giant magneto-impedance(GMI) in soft magnetic materials has opened new horizon in the development of micro-magnetic sensors operating at nano-Tesla range. A new type of asymmetric giant magneto impedance (A-GMI)sensor was developed and the performance of the sensowas carefully studied. This paper presents a design of linear magnetic sensor based on AGMI in Co68.15 Fe4.35Si12.5B15 wire s-subjected to a high frequency pulse current, which demonstrates a considerable asymmetry and enhanced sensitivity. Su-sequent, a novel approach, adopting rotary ellipsoid witharray of magnetic dipole, is used for the modeling of the field distribution of the battlefield ferromagnetic target, especially for tank. On account of amorphous wire's characteristics, th-e research of the paper provides a promising and effective w-ay to improve the performance for detecting and recognizingthe target and makes it possible for the microminiaturization of the micro-magnetic fuze system. ©2009 IEEE.

Empirical mode decomposition (EMD) can adaptively separate the intrinsic oscillatory modes of signals into a finite number of intrinsic mode functions (IMFs). IMFs will lose their physical meaning when mode mixing phenomenon occurs. In this paper, we first analyze the relationship between mode mixing and intermittency in signals. We then introduce a new type of mode mixing which is not caused by intermittency in signals. Finally, we argue that the time-varying extrema sampling rate is the essential reason of mode mixing. © 2009 IEEE.

defence technology（防务技术） 2009年第3期5卷 175-180页

作者：孙骥邓甲昊蔡克荣 National Key Laboratory of Mechatronic Engineering and Control Beijing Institute of Technology

A novel sensor for micro-magnetic field detection is proposed based on the physical characteristics and giant magneto-impedance (GMI) effect of Fe-Co-Si-B amorphous wires. The sensor circuit ensures high sensitivity,high detection precision,fast response and small power consumption. The signal processing circuit taking complex programmable logic device (CPLD) as core chip not only improves the identification ability for pseudo ferromagnetic objects,but also ensures the real-rime response. It is the foundation for the proposed sensor to serve widely in military and civil. By using its high sensitivity for geomagnetism variation,as an application example,the sensor is used to compare and analyze different cars.
