Stability Analysis of a Dynamic System under Random Parametric Excitation
불규칙 매개변수 가진을 받는 동적시스템의 안정성 해석
- Published : 1997.04.01
Abstract
Investigation is performed on the stability of general form of dynamic system whose damping and stiffness are varying in irregular manner along time, which is a preliminary result in the course of research on the characteristic and the control of the stochastic system. The governing equation of the 'parametric' system is derived via F-P-K approach in stochastic sense. The influence on the stability due to the magnitude of auto power spectral density and cross power spectral density of random variation of system parameters is studied and the region is surveyed.
