Abstract :
In this paper, we propose a state space approach to the decomposition of linear periodic time-varying (LPTV) systems. It decomposes an LPTV system into two subsystems: the stable LPTV subsystem and the unstable LPTV subsystem. An anti-causal realization for the unstable LPTV subsystem is further developed for providing stable numerical computation of the unstable system output
