摘要:
We show by means of examples that global complete observability and global stabilizability by state feedback are not sufficient to guarantee global stabilizability by dynamic output feedback. We show that a main obstruction is related to 'unboundedness unobservability'. This is that some unmeasured state components may escape in finite time whereas the measurements remain bounded.
