【Abstract】 The robust state observer design problem for uncertain singular systems with D_stability constraints is discussed. A method of designing the singular robust state observer is presented based on some parameter matrix inequalities and the generalized inverse theory, so that the singular state estimation system is regular, impulse_free and can ensure the finite poles being located within a prespecified circular region for all admissible parameter uncertainties. Thus, the observation process possesses the desired robustness transient property. Conditions for the existence of a desired robust state observer gain are given, and the analytical expression of such an observer gain is obtained更多还原
