Abstract: The equilibrium points of control systems with saturated inputs are defined. Based on these definitions, all kinds of the equilibrium points are analyzed in control systems with single saturated input. By the above facts, it is necessary in analyzing globally asymptotical stability of the origin that the other asymptotical stability equilibrium points are false ones.

Key words: single saturated input, true equilibrium points, false equilibrium points, commuting matrices, stability, asymptotical stability

摘要: 首先引入了饱和系统平衡点的分类。在此基础上,论证了单饱和输入下,开环,闭环均稳定或其一稳定时的平衡点的分布规律及判别准则;最后指出,当原点全局渐近稳定时,其余非零稳定平衡点均为伪平衡点的必要性。

关键词: 单饱和输入, 真平衡点, 伪平衡点, 可交换, 稳定, 渐近稳定
