... exponent Floquet multiplier Many important dynamic systems can be modeled as linear time-periodic (LTP), and it is exceedingly important to discover and accurately model this character since such a system can exhibit parametric resonances, which are not present for a linear time-invariant (LTI...

... ̃ ] , [ C ̃ ] , and [ K ̃ ] are the modified mass, damping, and stiffness matrices, respectively. Following their definition, it is clear that the Floquet multipliers are the eigenvalues of matrix [ D ] , a derivative operator, which can determine the stability of the periodic...
