This paper considers linear time-invariant decentralized singular systems which are either nonregular or, if they are regular, they have impulsive modes. It derives algebraic necessary and sufficient conditions for making a singular system both regular and impulsefree by decentralized output feedback control laws and decentralized proportional-plus-derivative output feedback control laws.

This is a proposal for a model and an architecture for decentralized process centered environments, supporting collaboration and concerted eeorts among geographically-dispersed teams { each team with its own autonomous process { with emphasis on exible control over the degree of collaboration and autonomy provided. The focus is on decentralized process modeling and on decentralized process enac...

This paper provides a new approach to decentralized failure-tolerant control using passivitybased stability conditions. A controller design method is developed to achieve both decentralized unconditional stability (a transformed passivity condition) and user-specified H2 performance. The control synthesis problem is solved by using successive semidefinite programming. The proposed method is ill...
