| 中文摘要 |
| 本文将对一类不确定系统提出推广的波波关判据，这类系统的线性部分乃诸顶点模型的凸组合，而非线性函数是处于某扇区内。判断说：不确定系统是某扇区绝对稳定的如果存在一条公共的波波夫直线使所有顶点系统的修正奈氏曲线位于这直线右侧。 |
| 英文摘要 |
| An extended Popov criterion will be presented for a class of nonlinear uncertain systems in which linear parts are the convex combination of vertex models, and the nonlinear functions lie within a sector. The criterion says that the uncertain system is absolutely stable in some sector if there exists a common Popov line such that the modified Nyquist loci of all vertex systems lie within the right of the line. |
