Output Feedback Admissible Control for Singular Systems: Delta Operator (Discretised) Approach

East Asian Journal on Applied Mathematics (2017)

Xin-zhuang Dong Mingqing Xiao

Abstract Singular systems simultaneously capture the dynamics and algebraic constraints in many practical applications. Output feedback admissible control for singular systems through a delta operator method is considered in this article. Two novel admissibility conditions, derived for the singular delta operator system (SDOS) from a singular continuous system through sampling, can not only produce unified admissibility for both continuous and discrete singular systems but also practical procedures. To solve the problem of output feedback admissible control for the SDOS, an existence condition and design procedure is given for the determination of a physically realisable observer for the state estimation, and then a suitable state-feedback-like admissible controller design based on the observer is developed. All of the conditions presented are necessary and sufficient, involving strict linear matrix inequalities (LMI) with feasible solutions obtained with low computational costs. Numerical examples illustrate our approach.

Robust strictly dissipative control for discrete singular systems

IET Control Theory and Applications (2007)

Xin-zhuang Dong

The problem of strictly dissipative control for discrete singular systems with or without parameter uncertainties is focused. A necessary and sufficient condition in terms of linear matrix inequalities (LMIs) is derived guaranteeing the admissibility and strict dissipativeness of a linear discrete singular system. Then, the existence condition of a state feedback strictly dissipative controller is given by using matrix inequalities (MIs). As for an uncertain discrete singular system, the uncertainties are assumed to be time-invariant and norm-bounded appearing in both the state and input matrices. A sufficient condition is obtained such that the uncertain system is generalised quadratically stable and strictly dissipative. Moreover, a state feedback robust strictly dissipative controller is also constructed by using the solution of MIs.

Robust H∞ performance control of uncertain SDOSs

Wen Wang Xin-zhuang Dong Teng Zhang

This paper investigates uncertain SDOSs (singular delta operator systems), regarding robust H∞ control and robust H∞ performance analysis. To ensure robust admissibility, we introduce the definition of generalized quadratic admissibility. Through LMI (linear matrix inequality), with the support of a necessary and sufficient condition, an uncertain singular delta operator system is generalized quadratically admissible with a prescribed performance. Then, based on these conclusions, the design problem of a robust H∞ controller is considered for uncertain SDOSs. In terms of an LMI, the existence condition of a suitable robust H∞ controller is derived, and the corresponding design method is also presented through the solution to the LMI. Also, a numerical example is adopted to show the efficiency of the theoretical results in this paper through Matlab-LMI toolbox.

LMI‐based H _∞ control for linear singular discrete systems: a novel method

IET Control Theory and Applications (2013)

Xin-zhuang Dong

This study investigates the problem of state feedback H∞ control for linear singular discrete systems. First, a novel admissibility condition and then a new bounded real lemma are proposed for linear singular discrete systems. Then, the existence condition and explicit expression of a desirable state feedback H∞ controller are obtained based on the above results. It should be pointed out that all the conditions in this study are necessary and sufficient and in the form of strict linear matrix inequalities that can be solved easily. Finally, some numerical examples are provided to illustrate the effectiveness of the theoretical results in this study.

Xin-zhuang Dong Mingqing Xiao

This paper investigates the problem of H _∞ performance analysis for singular systems through delta operator method. A novel admissibility condition is developed for singular delta operator systems. Based on the above result, two conditions are established for a singular delta operator system to be admissible with an H _∞ performance. All of the conditions appeared in this paper are necessary and sufficient, characterized by a set of strict linear matrix inequalities whose feasible solutions can be obtained easily by matlab-LMI toolbox. A numerical example is also provided to illustrate the effectiveness of the theoretical results in the paper.

Key techniques of seismic prediction for Paleozoic bauxite reservoirs, Ordos Basin

Rujie He Fei Li Guoliang Du Wenqi Zhao Bo Liu

Summary A major breakthrough has been achieved in natural gas exploration of bauxite of Taiyuan Formation in southwest margin of Ordos Basin, opening up a new field of gas exploration. As a new gas reservoir, the research on bauxite is still relatively few. A set of technical process suitable for bauxite reservoir prediction has been developed based on the bauxite data in Ordos Basin. Firstly, the interference of overlying coal seam is eliminated by removing the strong reflection to obtain an obvious seismic response of bauxite in Taiyuan Formation. Combined with paleo-geomorphology, geostatistics inversion method based on mixed Gaussian prior distribution is used to accurately characterize the bauxite favourable zone. The coincidence rate between the high-quality reservoirs predicted by the proposed seismic procedure and the actual posterior drilling is as high as 85%, which well solves the prediction issue of the new type of gas reservoirs, and provides great seismic technical support for the rolling development evaluation of gas field.
