Abstract :
This paper addresses the effects of synchronization errors in two interconnected discrete time systems represented in state space with small clock frequency mismatches. An event based discrete time index is used to capture the dynamics of the arising system. In a second step, the stability of the overall system is analyzed and compared to the stability of both the perfectly synchronized system (with identical clock signals) and the synchronized system with a non-zero phase difference between the two clock signals.
