英文摘要 |
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. |
