Abstract :
The author uses polynomial theory to analyze the basic properties of decentralized control descriptor systems. Applying a local derivative and proportional output feedback to the systems, its closed loop characteristic polynomial may be written as a linear combination of a group of polynomials, which are derived from the system matrices. From this some necessary and sufficient conditions for the systems to possess infinite decentralized fixed modes (INDFMs), impulsive decentralized fixed modes (IMDFMs) and generalized and decentralized fixed modes (GDFMs) are obtained. Similarly, the notions of infinite decentralized controllability (INDC), impulsive decentralized controllability (IMDC), and reachable decentralized controllability (RDC) are characterized. The problem of pole placement for the systems is discussed
