observer design and output feedback stabilization for linear singular time-delay systems with unknown inputs

引用

控制理论与应用（英文版） 2008年第2期6卷 177-183页

作者： Peng CUI Chenghui ZHANG School of Control Science and Engineering Shandong University Jinan Shandong 250061 China

The design of a functional observer and reduced-order observer with internal delay for linear singular timedelay systems with unknown inputs is discussed. The sufficient conditions of the existence of observers, which are normal linear time-delay systems, and the corresponding design steps are presented via linear matrix inequality（LMI）. Moreover, the observer-based feedback stabilizing controller is obtained. Three examples are given to show the effectiveness of the proposed methods.

A functional observer design method is presented for one-sided Lipschitz nonlinear systems. The existence conditions of a functional observer are obtained by a rank condition and solving a linear matrix inequality. Furthermore, a design method for gain matrices of the functional observer is presented. Finally, a numerical example is given to illustrate the effectiveness of the proposed design technique.

第40届中国控制会议

作者： Yujie Zhao Cong Lin Linxin Meng Xiushan Cai College of Physics and Electronic Information Engineering Zhejiang Normal University

This paper considers functional observer design for a class of nonlinear systems with incremental quadratic constraints. We construct a functional observer by injecting both the linear and nonlinear output error terms into the observer systems. Sufficient conditions ensuring exponential convergence of the observer error are established by a rank condition and solving a linear matrix inequality. The design approach for gain matrices of the proposed observer is obtained. Finally, the effectiveness of the proposed design approach is illustrated by an example.
