摘要:
设反馈控制系统为
y(s)=G(s,θ)u(s)(1)
u(s)=-K(s)y(s)+v(s). (2)
本文的主要结果如下:
当G(s,θ)在θ=θ0处零实部不升阶时,存在反馈控制(2),使得闭环稳定θ=θ.处
是结构稳定的一个充分必要条件为G(s,θ)在θ=θa处,正实部不是本质的升阶;当G(s,θ)
的零实部升阶时,这条件仅是必要的.
Abstract:
Consider the feedbacd control system
y(s)=G(s,θ)(1)
u(s)=-K(s)y(s)+v(s). (2)
In this paper we obtained following result:
When zero-real part of G(s,θ) at θ=θ0 is not ascending order the feedbacd control
(2)exists such that closed loop stability is structurally stable at θ=θ0 if and only if positive
real part G(s,θ) atθ=θ0 is not essential ascending order. When zero-real prat of
G(s,θ) at θ=θ0 is ascending order this condition is only necessary.
