摘要
. 研究了具有负反馈和正广义线性部分的非线性系统的全局(绝对)稳定性问题。分析了正广义线性系统的转移矩阵。非线性部分的特性u = f (e)满足k 1 e∙f (e)∙k 2 e对某正k 1, k 2的条件。证明了如果正描述子线性部分的Nyquist图位于圆的右侧,则非线性反馈系统是全局渐近稳定的
Global stability of nonlinear feedback systemswith positive descriptor linear parts
. The global (absolute) stability of nonlinear systems with negative feedbacks and positive descriptor linear parts is addressed. Transfer matrices of positive descriptor linear systems are analyzed. The characteristics u = f ( e ) of the nonlinear parts satisfy the condition k 1 e ∙ f ( e ) ∙ k 2 e for some positive k 1 , k 2 . It is shown that the nonlinear feedback systems are globally asymptotically stable if the Nyquist plots of the positive descriptor linear parts are located in the right-hand side of the circles
