Abstract :
The effect of sampling on decentralized fixed modes is analyzed. Decentralized fixed modes are classified as being "structured" and "unstructured". It is shown that for almost all sampling intervals the unstructured decentralized fixed modes will no longer exist in a system after the introduction of sampling. This implies that a continuous-time system with unstable decentralized fixed modes may still be stabilized with digital controllers for almost all sampling intervals.
