Abstract :
The subject area of this paper is discrete-time linear time-invariant systems composed of subsystems whose state updating is asynchronous due to the clock signal arriving with delays. This leads to the synchronization error identification problem which is to find from a trajectory of the system the order in which the subsystems´ states are updated. A solution to this problem based on a direct search over all possible synchronization errors is developed together with conditions for its uniqueness.
