摘要

This technical note addresses the existence of a common linear copositive Lyapunov function (CLCLF) for continuous-time switched positive linear systems. Two necessary and sufficient conditions for the existence of a CLCLF are provided. One condition shows that the existence of a CLCLF for a family of $ntimes n$-dimensional Metzler matrices can only be determined by $n-1$ lower dimensional Hurwitz matrices. The other condition further shows that the existence of a CLCLF is also determined by $n-1$ characteristic constants, which gives an easily verifiable computation algorithm without checking a large amount of Metzler Hurwitz matrices.
