,Introduction Linearity—A Shangri-la,s ubiquitous nonlinearity, we are nevertheless lured by the power of eigenvalues to describe a system’s dynamics. Their compact explanation of an aircraft’s Dutch Roll or the attenuation in an operational amplifier is satisfying and conclusive. That they are unique to the linear world and do not exi机构 发表于 2025-3-25 21:33:37

Liapunov Stability,ness to guarantee stability. In the linear case this is sufficient; in the nonlinear case we need to be more specific. The concepts of local, global, absolute, uniform, and asymptotic stability will be defined in Section 6.2.2, and examples given of each. Each depends upon regions of validity of the造反,叛乱 发表于 2025-3-26 12:38:42
