摘要：
This paper studies observer design for continuous-time linear descriptor systems. Based on the stability of positive system, a linear matrix inequality based direct design method of interval observer is proposed for descriptor systems. The proposed method is further improved by introducing more degrees of design freedom to obtain relaxed design conditions and a broader application scope of the interval observer. The proposed method is independent of coordinate transformation and is a direct design approach. Finally, two numerical examples are simulated to verify the effectiveness of the proposed method. © 2018, Editorial Department of Control Theory & Applications South China University of Technology.
